Overview

MC74VHC259 8-Bit Addressable Latch/1-of-8 Decoder CMOS Logic Level Shifter with LSTTL−Compatible Inputs The MC74VHC259 is an 8−bit Addressable Latch fabricated with silicon gate CMOS technology.
It achieves high speed operation similar to equivalent Bipolar Schottky TTL devices while maintaining CMOS low power dissipation.
The VHC259 is designed for general purpose storage applications in digital systems.
The device has four modes of operation as shown in the mode selection table.
.
In the addressable latch mode, the data on Data In is written into the addressed latch.
The addressed latch follows the data input with all non−addressed latches remaining in their previous states.
In the memory mode, all latches remain in their previous state and are unaffected by the Data or Address inputs.
In the one−of−eight decoding or demultiplexing mode, the addressed output follows the state of Data In with all other outputs in the LOW state.
In the Reset mode, all outputs are LOW and unaffected by ...
