General 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 non-inverting 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.

Key Features
