They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT573 are octal D-type transparent latches featuring separate D-type inputs for each latch and 3-state outputs for bus oriented applications. A latch enable (LE) input and an output enable (OE) input are common to all latches. The “573” consists of eight D-type transparent latches with 3-state true outputs. When LE is HIGH, data at QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns 74HC/HCT573 the Dn inputs enter the latches. In this condition the latches are tr……
