Product Summary

The 74HC574N is a high-speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL). The 74HC574N is specified in compliance with JEDEC standard no. 7A. The 74HC574N is octal D-type flip-flops featuring separate D-type inputs for each flip-flop and non-inverting 3-state outputs for bus oriented applications. A clock (CP) and an output enable (OE) input are common to all flip-flops.
