IN74ACT20
IN74ACT20 is Dual 4-Input NAND Gate manufactured by IK Semiconductor.
TECHNICAL DATA
Dual 4-Input NAND Gate
High-Speed Silicon-Gate CMOS
The IN74ACT20 is identical in pinout to the LS/ALS20, HC/HCT20. The IN74ACT20 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
- TTL/NMOS patible Input Levels
- Outputs Directly Interface to CMOS, NMOS, and TTL
- Operating Voltage Range: 4.5 to 5.5 V
- Low Input Current: 1.0 µA; 0.1 µA @ 25°C
- Outputs Source/Sink 24 m A
