MC74HCT574A
Octal 3−State Noninverting
D Flip−Flop with
LSTTL−Compatible Inputs
High−Performance Silicon−Gate CMOS

MARKING
The MC74HCT574A is identical in pinout to the LS574. This
device may be used as a level converter for interfacing TTL or NMOS
outputs to High Speed CMOS inputs.
DIAGRAMS
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.

The HCT574A is identical in function to the HCT374A but has the
flip−flop inputs on the opposite side of the package from the outputs to
facilitate PC board layout.
