Octal D-type transparant latch; 3-state
Rev. 4 — 5 March 2019
Product data sheet
1. General description
The 74AHC373 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. 7-A.
The 74AHC373 consists of eight D-type transparent latches featuring separate D-type inputs for
each latch and 3-state true outputs for bus oriented applications. A latch enable input (LE) and an
output enable input (OE) are common to all latches.
When pin 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 Dn input changes.
When pin LE is LOW, the latches store the information that is present at the Dn inputs, after a
set-up time preceding the HIGH-to-LOW transition of LE.
When pin OE is LOW, the contents of the 8 latches are available at the outputs. When pin 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 74AHC373 is functionally identical to the 74AHC573; 74AHCT573, but has a different pin
arrangement.

Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
