HD74HC574 Datasheet

HD74HC574 Octal D-type Flip-Flops

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.

Features

• High Speed Operation: tpd (Clock to Output) = 13 ns typ (CL = 50 pF)
