74HC573; 74HCT573  
Octal D-type transparent latch; 3-state  
Rev. 6 — 26 January 2015  
Product data sheet  
1. General description  
The 74HC573; 74HCT573 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 74HC573; 74HCT573 has octal D-type transparent latches featuring separate D-type  
inputs 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. In this condition, the latches are  
transparent, i.e. a latch output changes state each time its corresponding D input  
changes.  
When LE is LOW the latches store the information that was present at the D-inputs a  
set-up time preceding the HIGH-to-LOW transition of LE. When OE is LOW, the contents  
of the 8 latches 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  
latches.  
The 74HC573; 74HCT573 is functionally identical to:  
74HC563; 74HCT563, but inverted outputs  
74HC373; 74HCT373, but different pin arrangement  
2. Features and benefits  
Input levels:  
For 74HC573: CMOS level  
For 74HCT573: TTL level  
Inputs and outputs on opposite sides of package allowing easy interface with  
microprocessors  
Useful as input or output port for microprocessors and microcomputers  
3-state non-inverting outputs for bus-oriented applications  
Common 3-state output enable input  
Multiple package options  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115-A exceeds 200 V  
Specified from 40 C to +85 C and from 40 C to +125 C
