TECHNICAL DATA
IN74HC20A
Dual 4-Input NAND Gate
High-Performance Silicon-Gate CMOS
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
