HD74HCT564, HD74HCT574
Octal D-type Flip-Flops (with 3-state outputs)
REJ03D0670–0200
(Previous ADE-205-560)
Rev.2.00
Mar 30, 2006
Description
These devices are positive edge triggered flip-flops. The difference between HD74HCT564 and HD74HCT574 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 control (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.
