74HC564
Datasheet
General description
The 74HC564 is a high-speed Si-gate CMOS device and is pin compatible with low-power Schottky TTL (LSTTL). The 74HC564 is specified in compliance with JEDEC standard no. 7A.
The 74HC564 is a octal D-type flip-flop featuring separate D-type inputs for each flip-flop and inverting 3-state outputs for bus oriented applications. A clock (CP) and an output enable (OE) input are common to all flip-flops.
The 8 flip-flops will store the state of their individual D-inputs that meet the set-up and hold times requirements on the LOW-to-HIGH CP transition. When OE is LOW, the contents of the 8 flip-flops are available at the outputs. When OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops.
The 74HC564 is functionally identical to the 74HC574 but has inverting outputs. The 74HC564 is functionally identical to the 74HC534, but has a different pinning.
