8- -Bit Addressable

Latch/1- -of- -8 Decoder

CMOS Logic Level Shifter

silicon gate CMOS technology. It achieves high speed operation similar to

equivalent Bipolar Schottky TTL devices while maintaining CMOS low

power dissipation.

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 the address and data inputs. When operating the

VHC259 as an addressable latch, changing more than one bit of the

address could impose a transient wrong address. Therefore, this should

only be done while in the memory mode.

up to 7 V are applied, regardless of the supply voltage. This allows the

MC74VHC259 to be used to interface 5 V circuits to 3 V circuits.
