TECHNICAL DATA
IN74ACT20
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 Compatible 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 mA
