Overview
The 74HCT573DB-Q100J, produced by Nexperia USA Inc., is an 8-bit D-type transparent latch with 3-state outputs. This device is part of the 74HCT series and is designed to meet the stringent requirements of automotive applications, having been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1). The 74HCT573DB-Q100J features latch enable (LE) and output enable (OE) inputs, allowing for flexible control over data storage and output states. When the LE input is HIGH, the latches are transparent, and the output will change with each change in the corresponding D-input. When LE is LOW, the latches store the information present at the inputs. A HIGH on the OE input causes the outputs to assume a high-impedance OFF-state, which does not affect the state of the latches.
