N74F259N latch: dual-function demux + addressable latch

The N74F259N blends a demultiplexer and an 8-bit latch into one clean package. In latch mode, each individual addressed latch follows your Data input and holds other bits steady. The demux mode lets the addressed output reflect the Data level while keeping the rest low. It supports random data entry, a shared reset, and serial-to-parallel flexibility. Designed for 5 V TTL systems, it’s compact in a through-hole 16-pin DIP. Obsolete—but still a tool for vintage or replacement use. Choose N74F259N and keep your designs running. Get yours today.
