74HC373; 74HCT373  
Octal D-type transparent latch; 3-state  
Rev. 5 — 13 December 2011  
Product data sheet  
1. General description  
The 74HC373; 74HCT373 is a high-speed Si-gate CMOS device and is pin compatible  
with Low-power Schottky TTL. It is specified in compliance with JEDEC standard no. 7A.  
The 74HC373; 74HCT373 is an octal D-type transparent latch 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 74HC373; 74HCT373 consists of eight D-type transparent latches with 3-state true  
outputs. When LE is HIGH, data at the Dn inputs enters the latches. In this condition the  
latches are transparent, i.e. a latch output will change 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 74HC373; 74HCT373 is functionally identical to:  
74HC563; 74HCT563: but inverted outputs and different pin arrangement  
74HC573; 74HCT573: but different pin arrangement  
2. Features and benefits  
3-state non-inverting outputs for bus oriented applications  
Common 3-state output enable input  
Functionally identical to the 74HC563; 74HCT563 and 74HC573; 74HCT573  
ESD protection:  
HBM JESD22-A114F exceeds 2 000 V  
MM JESD22-A115-A exceeds 200 V  
Specified from 40 C to +85 C and from 40 C to +125 C
