8-Bit Addressable
Latch/1-of-8 Decoder
CMOS Logic Level Shifter
with LSTTLCompatible Inputs
The MC74VHCT259 is an 8bit Addressable Latch fabricated with
silicon gate CMOS technology. It achieves high speed operation
similar to equivalent Bipolar Schottky TTL while maintaining CMOS
low power dissipation.
The internal circuit is composed of three stages, including a buffer
output which provides high noise immunity and stable output.
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 signal on
Data In is written into the addressed latch. The addressed latch follows
the data input with all nonaddressed 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
oneofeightdecoding 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 VHCT259 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.
The VHCT inputs are compatible with TTL levels. This device can
be used as a level converter for interfacing 3.3 V to 5.0 V because it
has full 5.0 V CMOS level output swings.
The VHCT259A input structures provide protection when voltages
between 0 V and 5.5 V are applied, regardless of the supply voltage.
The output structures also provide protection when VCC = 0 V. These
input and output structures help prevent device destruction caused by
supply voltageinput/output voltage mismatch, battery backup, hot
insertion, etc.
