HD74HC564 Description
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 positive going transitions of the clock (CK) input.
HD74HC564 Key Features
- High Speed Operation: tpd (Clock to Output) = 13 ns typ (CL = 50 pF) High Output Current: Fanout of 15 LSTTL Loads Wide
