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.
