1. General description

The 74HC573-Q100; 74HCT573-Q100 is an 8-bit D-type transparent latch with 3-state outputs.

The device features latch enable (LE) and output enable (OE) inputs. When LE is HIGH, data at

the inputs enter the latches. In this condition the latches are transparent, a latch output will change

each time its corresponding D-input changes. When LE is LOW the latches store the information

that was present at the inputs a set-up time preceding the HIGH-to-LOW transition of LE. A HIGH

on OE causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does

not affect the state of the latches. Inputs include clamp diodes. This enables the use of current

limiting resistors to interface inputs to voltages in excess of VCC.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
