The IC 74HC10 comes as smaller in size and offers much faster speed which makes it highly reliable in every kind of device. 74HC10 IC can be soldered directly to the circuit board or easily mounted on a 14-pin IC base. They perform the Boolean functions Y = A • B • C or Y = A + B + C in positive logic. 74HC10 Operates at a supply voltage of 7V. This IC is designed for operation over the full military temperature range of ?55°C to 125°C. 74HC10 has 14?pin. 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 logically low. On the other hand, a NAND gate yields a logical high only when all of its inputs are set to LOW.

When triggered, the output of the multivibrator goes high for a fixed period of time, after which it returns to its original state. The duration of the output pulse is determined by the values of an external resistor and capacitor connected to the IC. check out : CD4538 - Dual Precision Monostable Multivibrator IC Pinout: Pinout Of 74HC123 IC

74HC138 - 3-to-8 line Decoder/Demultiplexer IC The 74HC Series 74HC138 decoder utilizes advanced silicon-gate CMOS technology and is well suited to memory address decoding or data routing applications. The circuit features high noise immunity and low power consumption usually associated with CMOS circuitry, yet has speeds comparable to low-power Schottky TTL logic. The 74HC138 has 3 binary select inputs (A, B, and C). If the device is enabled, these inputs determine which one of the eight normally HIGH outputs will go LOW. Two active LOW and one active HIGH enable (G1, G2A, and G2B) are provided to ease the cascading of decoders. The decoder’s outputs can drive 10 low-power Schottky TTL equivalent loads, and are functionally and pin equivalent to the 74LS138. All inputs are protected from damage due to static discharge by diodes to VCC and the ground. Pinout: Pinout Of 74HC138 IC Also check the 74139 Dual Decoder-Demux IC . It is a digital logic IC used to convert a two-line binary input signal into one of four output signals. The IC has two active-low enable inputs (E1 and E2) and two data inputs (D1 and D2). When both enable inputs are high, the outputs are inactive, and when one of the enabled inputs is low, the corresponding data input is passed through to the outputs.

Hex Schmitt Trigger Inverter IC - 74HC14 The 74HC14 is a hex Schmitt trigger inverter integrated circuit (IC) with six independent Schmitt trigger inputs. Each input has an active high and active low output. The 74HC Series 74HC14 contains six independent gates each of which performs the logic INVERT function. Each input has hysteresis which increases the noise immunity and transforms a slowly changing input signal to a fast-changing, jitter-free output. Pinout : Pinout Of 74HC14 IC

Decimal to BCD Priority Encoder IC - 74HC147 The 74HC Series 74HC147 are high-speed silicon-gate CMOS devices and are pin-compatible with low-power Schottky TTL (LSTTL). The 74HC147 9-input priority encoders accept data from nine active LOW inputs (l1 to l9) and provide binary representation on the four active LOW inputs (Y0 to Y3). A priority is assigned to each input so that when two or more inputs are simultaneously active, the input with the highest priority is represented on the output, with the input l9 line having the highest priority. These devices provide the 10-line to 4-line priority encoding function by use of the implied decimal “zero”. The “zero” is encoded when all nine data inputs are HIGH, forcing all four outputs HIGH.

74HC165 - 8-Bit Parallel In/Serial Out Shift Register IC The 74HC Series 74HC165 high-speed PARALLEL-IN/SERIAL-OUT SHIFT REGISTER utilizes advanced silicon-gate CMOS technology. It has the low power consumption and high noise immunity of standard CMOS integrated circuits, along with the ability to drive 10 LS-TTL loads. This 8-bit serial shift register shifts data from QA to QH when clocked. Parallel inputs to each stage are enabled by a low level at the SHIFT/LOAD input. Also included is a gated CLOCK input and a complementary output from the eighth bit. Clocking is accomplished through a 2-input NOR gate permitting one input to be used as a CLOCK INHIBIT function. Holding either of the CLOCK inputs high inhibits clocking, and holding either CLOCK input low with the SHIFT/LOAD input high enables the other CLOCK input. Data transfer occurs on the positive-going edge of the clock. Parallel loading is inhibited as long as the SHIFT/LOAD input is HIGH. When taken LOW, data at the parallel inputs are loaded directly into the register independent of the state of the clock. The 74HC logic family is functionally as well as pin-out compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and the ground. check out : 4-bit Parallel-Access Shift Register IC - 74HC95 Pinout: Pinout Of 74HC165
