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. when a high logic level is applied to the output cotrol
(OC) input, all outputs go to a high impedance state, regardless of what signals are present at the other
inputs and the state of the storage elements.


1. High Speed Operation: tpd (Clock to Output) = 13 ns typ (CL = 50 pF)
2. High Output Current: Fanout of 15 LSTTL Loads
3. Wide Operating Voltage: VCC = 2 to 6 V
4. Low Input Current: 1 μA max
5.  Low Quiescent Supply Current: ICC (static) = 4 μA max (Ta = 25°C)
