MC74AC259 - 8-BIT ADDRESSABLE LATCH

Download the MC74AC259 datasheet PDF. This datasheet also covers the MC74ACT259 variant, as both devices belong to the same 8-bit addressable latch family and are provided as variant models within a single manufacturer datasheet.

Description

The MC74AC259/74ACT259 has four modes of operation as shown in the Mode Selection Table.

In the addressable latch mode, data on the Data line (D) is written into the addressed latch.

( DataSheet : www.DataSheet4U.com ) MC74AC259 MC74ACT259 8ĆBit Addressable Latch The MC74AC259/74ACT259 is a high-speed 8-bit addressable latch designed for general purpose storage applications in digital systems. It is a multifunctional device capable of storing single line data in eight addressable latches, and also a 1-of-8 decoder and demultiplexer with active HIGH outputs. The device also incorporates an active LOW Common Clear for resetting all latches, as well as an active LOW Enable. It is functionally identical to the ALS259 8-bit addressable latch.
