MC74HC574A
Octal 3-State Noninverting
D Flip-Flop
High−Performance Silicon−Gate CMOS
The MC74HC574A is identical in pinout to the LS574. The device
inputs are compatible with standard CMOS outputs; with pull−up
resistors, they are compatible with LSTTL outputs.
Data meeting the set−up 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 HC574A is identical in function to the HC374A but has the
flip−flop inputs on the opposite side of the package from the outputs to
facilitate PC board layout.
