Overview
The 74AHC573D,112 from Nexperia USA Inc. is an 8-bit D-type transparent latch with 3-state outputs. This integrated circuit is part of the 74AHC family, known for its high-speed CMOS logic. The device 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 follows the 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, without affecting the stored data in the latches.
