8−Bit Addressable  
Latch/1−of−8 Decoder  
CMOS Logic Level Shifter  
with LSTTL−Compatible Inputs

MARKING  
The MC74VHCT259 is an 8−bit 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.  
DIAGRAMS

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 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−eightdecoding 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.
