IC 7400 (Quad 2-input NAND gates)

IC 7400 is the most popular logic family in integrated circuits. Texas Instruments has introduced the first logic chip namely SN5400 series TTL (transistor-transistor logic) in the year 1964. Later on, SN7400 series logic chip was introduced in the year 1966. These chips were gained above 50% of the logic chip market quickly. Finally, these ICs are becoming consistent electronic components. In the past decade, there are different pin-compatible generations with descendant families were developed to give support for lower-power supply voltages, low-power CMOS technology, & surface-mount packages. This article discusses an overview of IC 7400.

The IC 7400 can be built with a number of devices, which provides all from basic logic-gates, FFs (flip-flops), counters to ALU, and bus transceivers. The extended family of digital ICs is 7400 series ICs. This series ICs mainly include different discreet logic chips like logic gates along with different registers, RAM units, and decoders.
