SL74HCT374
Octal 3-State Noninverting D Flip-Flop
High-Performance Silicon-Gate CMOS
The SL74HCT374 is identical in pinout to the LS/ALS374.
The SL74HCT374 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.
