HD74HC574 Datasheet (Hitachi Semiconductor)

HD74HC574, Octal D-type Flip-Flop

These devices are positive edge triggered flip-flops.

The difference between HD74HC564 and HD74HC574 is only that the former has inverting outputs and the latter has noninvertering outputs.

Data at the D inputs, meeting the set-up and hold time requirements, are transferred to the Q or Q outputs on
