IN74AC20
IN74AC20 is Dual 4-Input NAND Gate manufactured by IK Semiconductor.
TECHNICAL DATA
Dual 4-Input NAND Gate
High-Speed Silicon-Gate CMOS
The IN74AC20 is identical in pinout to the LS/ALS20, HC/HCT20. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALS outputs.
- Outputs Directly Interface to CMOS, NMOS, and TTL
- Operating Voltage Range: 2.0 to 6.0 V
- Low Input Current: 1.0 µA; 0.1 µA @ 25°C
- High Noise Immunity Characteristic of CMOS Devices
- Outputs Source/Sink 24 m A
