MC74HCT374A
Octal 3-State Noninverting
D Flip-Flop with
LSTTL-Compatible Inputs
High–Performance Silicon–Gate CMOS
The MC74HCT374A may be used as a level converter for
interfacing TTL or NMOS outputs to High–Speed CMOS inputs.
The HCT374A is identical in pinout to the LS374.
Data meeting the setup and hold time is clocked to the outputs with
the rising edge of Clock. The Output Enable does not affect the state 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.
The HCT374A is identical in function to the HCT574A, which has
the input pins on the opposite side of the package from the output pins.
This device is similar in function to the HCT534A, which has
inverting outputs.
