74HC573

High-speed Si-gate CMOS

The 74HC573is a high-speed Si-gate CMOS device and is pin compatiblewith Low-power Schottky TTL (LSTTL). It has octal D-type transparent latches featuring separate D-typeinputs for each latch and 3-state true outputs for bus oriented applications. A latch enable(LE) input and an output enable (OE) input are common to all latches.When LE is HIGH, data at the Dn inputs enter the latches.
