DUAL 4-INPUT AND GATE
High-Speed Silicon-Gate CMOS
The IN74ACT21 is identical in pinout to the LS/ALS21,
HC/HCT21. The IN74ACT21 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
