CD4059 - Programmable Divide-by-N Counter IC The CD4x Series CD4059 standard "A" Series types are divide-by-N down-counters that can be programmed to divide an input frequency by any number "N" from 3 to 15,999. The output signal is a pulse one clock-cycle wide occurring at a rate equal to the input frequency divided by N. This single output has TTL drive capability. The down-counter is preset by means of 16 jam inputs. The three Mode-Select Inputs Ka, Kb, and Kc determine the modulus ("divide-by" number) of the first and last counting sections. Every time the first (fastest) counting section goes through one cycle, it reduces by 1 the number that has been preset (jammed) into the three decades of the intermediate counting section and into the last counting section, which consists of flip-flops that are not needed for operating the first counting section. For example, in the 2 modes, only one flip-flop is needed in the first counting section. Therefore the last counting section has three flip-flops that can be preset to a maximum count of seven with a place value of thousands. If 10 is desired for the first section, Ka is set to 1, Kb to 1, and Kc to 0. Jam Inputs J1, J2, J3, and J4 are used to preset the first counting section and there is no last counting section. The intermediate counting section consists of three cascaded BCD decade (10) counters presettable by means of Jam Inputs J5 through J16. This device is particularly advantageous in communication digital frequency synthesis (VHF, UHF, FM, AM, etc.) where programmable divide-by-"N" counters are an integral part of the synthesizer phase-locked-loop sub-system. The CD4059 can also be used to perform the synthesizer "Fixed Divide-by-R" counting function. It is also useful in general-purpose counters for instrumentation functions such as totalizers, production counters, and "time-out" timers. The CD4059B-series types are supplied in 24-lead dual-in-line plastic packages (E suffix), and 24-lead small-outline packages (M and M96 suffixes).

All inputs are protected against static discharge. These gates may be used as hex buffers, CMOS to DTL or TTL interface or as CMOS current drivers. Conversion ranges are from 3V to 15V providing VCC ? VDD. The devices also have buffered outputs which improve transfer characteristics by providing very high gain. The CD4x Series CD4010 Hex Buffer/Converters may be used as CMOS to TTL or DTL logic-level converters or CMOS high-sink-current drivers. The CD4010 types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), and 16-lead dual-in-line plastic packages (E suffix). check out : CD4050 - Hex Non-Inverting Buffer IC Applications: CMOS to DTL/TTL hex converter CMOS current "sink" or "source" driver CMOS high-to-low logic-level converter Multiplexer — 1 to 6 or 6 to 1

CD4012 Dual 4 Input NAND Gate IC feature a Propagation Delay Time of Max 250ns and Power Dissipation of  250mW. NAND gate is defined as a digital logic gate most commonly used in DLD applications. It is also sometimes referred to as a universal logic gate and used to implement any logic gate or expression in existence. In case, if any one of the inputs to the NAND gate switch to high, the output of the gate will always be logical low. On the other hand, a NAND gate yields a logical high only when all of its inputs are set to LOW. check out : Dual 4 Input AND Gate IC - CD4082 Pinout: Pinout of CD4012 IC Application Automotive Alarm system Data terminals Industrial controls Instrumentation Remote metering Medical Electronics Computers

CD4013 - Dual D Type Flip-Flop IC The CD4013 designed as a CMOS logic chip IC belongs to the CD4XXX IC series. The CD4013 device comprises two identical, independent data-type flip-flops. Each flip-flop comes with independent data, set, reset, and clock inputs, and Q and Q’ outputs. These devices are commonly used for shift register applications, and, by connecting Q output to the data input, for counter and toggle applications. The logic level present at the D input is transmitted to the Q output during the positive-going transition of the clock pulse. Moreover, the Setting or resetting of IC is independent of the clock and accomplished by a high level on the set or reset line, respectively.  The CD4013B is manufactured in 14-pin dual-inline plastic packages (E suffix), 14-pin small-outline packages (M, MT, M96, and NSR suffixes), and 14-pin thin shrink small-outline packages (PW and PWR suffixes). A D-type Latch/flip-flop is designed as a clocked latch that has two stable states. A D-type latch operates with a delay in input by one clock cycle. Thus, by cascading many D-type flip-flops delay circuits are often created, which are utilized in many applications like in digital television systems.  A D-type flip-flop is additionally mentioned as a D flip-flop or a delay flip-flop. The D flip-flop is an edge-triggered device that transfers input files to Q on a clock rising or falling edge. Data Latches are level sensitive devices like the data latch and therefore the transparent latch.

8-bit Up/Down Binary Counter IC - CD40193 The CD40193 IC up/down counters are monolithic complementary MOS (CMOS) integrated circuits. The CD40192BM and CD40192BC are BCD counters, while the CD40193BM and CD40193BC are binary counters. Counting up and counting down is performed by two count inputs, one being held high while the other is clocked. The outputs change on the positive-going transition of this clock. These CD4x Series IC counters feature preset inputs that are enabled when the load is a logical ‘‘0’’ and a clear which forces all outputs to ‘‘0’’ when it is at a logical ‘‘1’’. The counters also have to carry and borrow outputs so that they can be cascaded using no external circuitry. All inputs are protected against damage due to static discharge by clamps to VDD and VSS. check out : Divide by 8 Counter/Divider IC - CD4022 Pinout: Pinout of CD40193 IC Application Up/Down difference counting Multistage ripple counting Synchronous frequency divider A/D or D/A conversion BCD counting

14 Stage Ripple Carry Binary Counter IC - CD4020 The CD4020 IC is a ripple-carry binary counter. All counter stages are master-slave flip-flops.

Divide by 8 Counter/Divider IC - CD4022 The CD4022 IC is a 4-stage divide-by-8 Johnson counter with 8 decoded outputs and a carry-out bit. These counters are cleared to their zero counts by a logical ‘‘1’’ on their reset line. These counters are advanced on the positive edge of the clock signal when the clock enable signal is in the logical ‘‘0’’ state. The configuration of the CD4x Series CD4022 permits medium-speed operation and assures a hazard-free counting sequence. The 10/8 decoded outputs are normally in the logical ‘‘0’’ state and go to the logical ‘‘1’’ state only at their respective time slot. Each decoded output remains high for 1 full clock cycle. The carry-out signal completes a full cycle for every 10/8 clock input cycle and is used as a ripple to carry the signal to any succeeding stages. check out : 8-bit Up/Down Binary Counter IC - CD40193 Pinout: Pinout of CD4022 IC
