Product Summary

The 74HC574D is a high-speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. The 774HC574N is an octal D-type flip-flop 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.
