IN74HC20A
TECHNICAL DATA
Dual 4-Input NAND Gate
High-Performance Silicon-Gate CMOS
The IN74HC20A is identical in pinout to the LS/ALS20. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible 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
ORDERING INFORMATION IN74HC20AN Plastic IN74HC20AD SOIC TA = -55° to 125° C for all packages
