74HC20 Dual 4-input NAND Gate IC (7420 IC) DIP-14 Package

The 74HC20 is a 14 Pin Quad 4-Input NAND Gate IC. This device contains four independent gates each of which performs the logic NAND function. NAND gates utilize advanced silicon-gate CMOS technology to achieve operating speeds similar to LS-TTL gates with the low power consumption of standard CMOS integrated circuits. All gates have buffered outputs.

Description

The 74HC20 is a 14 Pin Quad 4-Input NAND Gate IC. This device contains four independent gates each of which performs the logic NAND function. NAND gates utilize advanced silicon-gate CMOS technology to achieve operating speeds similar to LS-TTL gates with the low power consumption of standard CMOS integrated circuits. All gates have buffered outputs.

All devices have high noise immunity and the ability to drive 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.


Features :-

  • Complies with JEDEC standard JESD7A
  • Low-power dissipation
