IN74ACT374

1

High-Speed Silicon-Gate CMOS

The IN74ACT374 is identical in pinout to the LS/ALS374,

HC/HCT374. The IN74ACT374 may be used as a level converter

for interfacing TTL or NMOS outputs to High Speed CMOS inputs.

Data meeting the setup and hold time is clocked to the outputs

with the rising edge of the Clock. The Output Enable input does

not affect the states of the flip-flops, but when Output Enable is

high, the outputs are forced to the high-impedance state; thus,

data may be stored even when the outputs are not enabled.

• 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
