Overview
The 74HC573DB,112 is an octal D-type transparent latch with 3-state outputs, manufactured by Nexperia USA Inc. This device is part of the 74HC573 and 74HCT573 series, which are designed for a wide range of digital logic applications. The latch 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, meaning the output will change in real-time with the input. When LE is LOW, the latches store the information present at the inputs just before the transition. A HIGH on the OE input causes the outputs to enter a high-impedance OFF-state, without affecting the stored data in the latches.
