Product data sheet
1. General description
The 74HC373-Q100; 74HCT373-Q100 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-Q100; 74HCT373-Q100 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-Q100; 74HCT373-Q100 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 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 74HC373-Q100; 74HCT373-Q100 is functionally identical to:
•
74HC573-Q100; 74HCT573-Q100: but different pin arrangement
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
