Overview
The 74HC573DB-Q100J, produced by Nexperia USA Inc., is an 8-bit D-type transparent latch with 3-state outputs. This integrated circuit is designed to store and transfer data efficiently, making it a crucial component in various digital systems. The device features latch enable (LE) and output enable (OE) inputs, allowing for precise control over data storage and output states. When the LE input is HIGH, the latches are transparent, and the output follows the input. When LE is LOW, the latches store the data present at the inputs. A HIGH on the OE input causes the outputs to enter a high-impedance OFF-state, which does not affect the stored data in the latches.
