74HCT574PW,118

The 74HC574; 74HCT574 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL. It is specified in compliance with JEDEC standard no. 7A. The 74HC574; 74HCT574 are octal D-type flip-flops featuring separate D-type inputs for each flip-flop and 3-state outputs for bus-oriented applications. A clock (CP) and an output enable 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 output enable is LOW the contents of the 8 flip-flops are available at the outputs. When output enable is HIGH, the outputs go to the high-impedance OFF-state. Operation of the output enable input does not affect the state of the flip-flops.
