An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or “chip”) of semiconductor material, normally silicon. The integration of large numbers of tiny transistors into a small chip results in circuits that are orders of magnitude smaller, cheaper, and faster than those constructed of discrete electronic components. The IC’s mass production capability, reliability and building-block approach to circuit design has ensured the rapid adoption of standardized ICs in place of designs using discrete transistors. ICs are now used in virtually all electronic equipment and have revolutionized the world of electronics. Computers, mobile phones, and other digital home appliances are now inextricable parts of the structure of modern societies, made possible by the small size and low cost of ICs
74F283 4-Bit Binary Full Adder with Fast Carry
The 74F283 high-speed 4-bit binary full adder with internal carry lookahead accepts two 4-bit binary words (A0–A3, B0–B3) and a Carry input (C0). It generates the binary Sum outputs (S0–S3) and the Carry output (C4) from the most significant bit. The 74F283 will operate with either active HIGH or active LOW operands (positive or negative logic).
7486 IC – Quad 2-Input EXOR GATE ICGeneral DescriptionThe 74HC86 exclusive OR gate utilizes advanced silicon-gate CMOS technology to achieve operating speeds similar to equivalent LS-TTL gates while maintaining the low power consumption and high noise immunity characteritic of standard CMOS integrated circuits. These gates are fully buffered and have a fanout of 10 LS-TTL loads. 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 ground.
7432 IC – Quad 2-Input OR Gate IC
– Four 2-Input Logic OR Gates in a 14-Pin DIP Package
– Outputs Directly Interface to CMOS, NMOS and TTL
– Large Operating Voltage Range

7446 BCD-TO-SEVEN-SEGMENT DECODERS/DRIVERS IC
The DM7446A and DM7447A feature active-LOW outputs designed for driving common-anode LEDs or incandescent indicators directly. All of the circuits have full ripple-blanking input/output controls and a lamp test input. Segment identification and resultant displays are shown on a following page. Display patterns for BCD input counts above nine are unique symbols to authenticate input conditions. All of the circuits incorporate automatic leading and/or trailing-edge, zero-blanking control (RBI and RBO). Lamp test (LT) of these devices may be performed at any time when the BI/RBO node is at a HIGH logic level. All types contain an overriding blanking input (BI) which can be used to control the lamp intensity (by pulsing) or to inhibit the outputs.
74161 Presettable synchronous 4-bit binary counter; asynchronous reset
These synchronous, presettable counters feature an internal carry look-ahead for application in high-speed counting designs. The 161 and 163 are 4-bit binary counters. The carry output is decoded by means of a NOR gate, thus preventing spikes during the normal counting mode of operation.
74HC4060 IC – 14-Stage Binary Ripple Counter IC (744060 IC)General DescriptionThe MM74HC4060 is a high speed binary ripple carry counter. These counters are implemented utilizing advanced silicon-gate CMOS technology to achieve speed performance similar to LS-TTL logic while retaining the low power and high noise immunity of CMOS.The MM74HC4060 is a 14-stage counter, which device increments on the falling edge (negative transition) of the input clock, and all their outputs are reset to a low level by applying a logical high on their reset input. The MM74HC4060 also has two additional inputs to enable easy connection of either an RC or crystal oscillator.
