Overview
The 74HCT573DB,112 is an octal D-type transparent latch with 3-state outputs, manufactured by NXP USA Inc. This integrated circuit is part of the 74HCT series, which is compatible with TTL (Transistor-Transistor Logic) levels. The device is designed to provide high-speed data storage and retrieval, making it suitable for a variety of digital logic applications.
The 74HCT573DB,112 features a transparent latch operation, meaning that the data at the inputs is transferred to the outputs when the latch enable (LE) input is high. When the LE input is low, the outputs are latched, and the data is stored even if the inputs change.
