Overview
The 74HC573PW,118 is an 8-bit D-type transparent latch with 3-state outputs, manufactured by Nexperia USA Inc. This device is designed to provide flexible data storage and output control, making it useful in various digital circuit applications. It features latch enable (LE) and output enable (OE) inputs, allowing for precise control over data flow 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 information present at the inputs. A HIGH on the active-low OE input causes the outputs to assume a high-impedance OFF-state, without affecting the latch state.
