High-Performance Silicon-Gate CMOS
The IN74ACT574 is identical in pinout to the LS/ALS574,
HC/HCT574. The IN74ACT574 may be used as a level converter
for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
Data meeting the setup 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, all
device outputs are forced to the high-impedance state; thus, data
may be stored even when the outputs are not enabled.
