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
