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.
