Description
The 74HC259PW,118 is a high-speed, silicon-gate CMOS 8-bit Addressable Latch. This versatile device functions as an 8-bit memory element that can be used for demultiplexing or as a general-purpose latch. It features a single data input (D), three address inputs (A0–A2), an active-LOW enable input (LE), and a master reset (MR) input.
The IC operates in two primary modes: Addressable Latch Mode (where the data input is latched into the addressed bit) and Memory Mode (where all outputs are held in their current state). It also includes a Clear function, which resets all eight latches to a LOW state simultaneously. This device is ideal for applications requiring individual control of multiple outputs from a single data bus.
