IN74HC20A Datasheet, PDF (1/5 Pages) Integral Corp. – Dual 4-Input NAND Gate High-Performance Silicon-Gate CMOS

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
