CD4029 - Binary Decade Up-Down Counter IC The CD4029 IC consists of a four-stage binary or BCD-decade up/ down counter with provisions for look-ahead carry in both counting modes. The inputs consist of a single CLOCK, CARRY-IN (CLOCK ENABLE), BINARY/DECADE, UP/DOWN, PRESET ENABLE, and four individual JAM signals. Q1, Q2, Q3, Q4, and a CARRY OUT signal are provided as outputs. A high PRESET ENABLE signal allows information on the JAM INPUTS to preset the counter to any state asynchronously with the clock. A low on each JAM line, when the PRESET-ENABLE signal is high, resets the counter to its zero counts. The counter is advanced one count at the positive transition of the clock when the CARRY-IN and PRE-SET ENABLE signals are low. Advancement is inhibited when the CARRY-IN or PRESET ENABLE signals are high. The CARRY-OUT signal is normally high and goes low when the counter reaches its maximum count in the UP mode or the minimum count in the DOWN mode provided the CARRY-IN signal is low. The CARRY-IN signal in the low state can thus be considered a CLOCK ENABLE. The CARRY-IN terminal must be connected to VSS when not in use. Binary counting is accomplished when the BINARY/DECADE input is high; the counter counts in the decade mode when the BINARY/DECADE input is low. The counter counts up when the UP/DOWN input is high, and down when the UP/DOWN input is low. Multiple packages can be connected in either a parallel clocking or a ripple-clocking arrangement as shown in Figure 17. Parallel clocking provides synchronous control and hence faster response from all counting outputs. Ripple-clocking allows for longer clock input rise and fall times.

555 Timer IC The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The ic 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide up to four timing circuits in one package. These 555 timer ICs are precision timing circuits capable of producing accurate time delays or oscillations. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. The threshold and trigger levels normally are two-thirds and one-third, respectively, of VCC. These levels can be altered by the use of the control voltage terminal. When the trigger input falls below the trigger level, the flip-flop is set and the output goes high. If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is reset and the output is low. The reset (RESET) input can override all other inputs and can be used to initiate a new timing cycle. When RESET goes low, the flip-flop is reset and the output goes low. When the output is low, a low-impedance path is provided between discharge (DISCH) and ground. The output circuit is capable of sinking or sourcing current up to 200 mA. The operation is specified for supplies of 5 V to 15 V. With a 5-V supply, output levels are compatible with TTL inputs. The NE555 is characterized for operation from 0°C to 70°C.

CD4099 - 8 bit Addressable Latch IC The CD4099 8-bit addressable latch IC is a serial-input, parallel-output storage register that can perform a variety of functions. Data are inputted to a particular bit in the latch when that bit is addressed (by means of input A0, A1, A2) and when WRITE DISABLE is at a low level. When WRITE DISABLE is high, data entry is inhibited; however, all 8 outputs can be continuously read independently of WRITE DISABLE and address inputs. A master RESET input is available, which resets all bits to a logic "0" level when RESET and WRITE DISABLE is at a high level. When RESET is at a high level, and WRITE RESET is at a low level, the latch acts as a 1-of-8 demultiplexer; the bit that is addressed has an active output that follows the data input, while all unaddressed bits are held to a logic "0" level. The CD4099 types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, MT, and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes). check out : Quad NOR R-S Latch Tri-state IC - CD4043 Pinout: Pin No Pin Name Description 1 Q7 Output Pin 7 of Latch 2 CL Clear Output Pin 3 D Data Input 4 E’ Enable Pin 5 A0 Input Pin 0 of Latch 6 A1 Input Pin 1 of Latch 7 A2 Input Pin 2 of Latch 8 VSS Source Supply 9 Q0 Output Pin 0 of Latch 10 Q1 Output Pin 1 of Latch 11 Q2 Output Pin 2 of Latch 12 Q3 Output Pin 3 of Latch 13 Q4 Output Pin 4 of Latch 14 Q5 Output Pin 5 of Latch 15 Q6 Output Pin 6 of Latch 16 VDD Drain Supply Applications: Multi-line decoders A/D converters

Dual 2-to-4 line Decoder/Demultiplexer IC - 74HC139 The 74HC Series 74HC139 comprises two separate two-line-to-four-line decoders in a single package. The active-low enable input can be used as a data line in demultiplexing applications. All of these decoders/demultiplexers feature fully buffered inputs, presenting only one normalized load to its driving circuit. All inputs are clamped with high-performance Schottky diodes to suppress line-ringing and simplify system design. These Schottky-clamped circuits are designed to be used in high-performance memory-decoding or data-routing applications, requiring very short propagation delay times. In high-performance memory systems, these decoders can be used to minimize the effects of system decoding. When used with high-speed memories, the delay times of these decoders are usually less than the typical access time of the memory. This means that the effective system delay introduced by the decoder is negligible.
