IK Semicon Co., Ltd 

TECHNICAL DATA

Dual 4-Input NAND Gate

High-Performance Silicon-Gate CMOS

IN74HC20A

The IN74HC20A is identical in pinout to the LS/ALS20. The device

inputs are compatible with standard CMOS outputs; with pullup resistors,

they are compatible with LS/ALSTTL outputs.

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2.0 to 6.0 V

• Low Input Current: 1.0 µA

• High Noise Immunity Characteristic of CMOS Devices
