NXP 74HC574D,652 SMD HCMOS Octal D-Type Flip-Flop Non-Inverting Tri-State SO-20

The 74HCT574D 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 (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 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.
