Overview
The 74HCT259PW,112 is an 8-bit addressable latch produced by Nexperia USA Inc. This integrated circuit is part of the 74HCT series and is designed to operate with TTL (Transistor-Transistor Logic) input levels. The device features four modes of operation: addressable latch, memory, 3-to-8 decoding or demultiplexing, and reset. It is particularly useful as a combined demultiplexer and 8-bit latch, offering serial-to-parallel capability and random data entry.
