MC74VHCT257A  
Quad 2-Channel Multiplexer  
with 3-State Outputs  
The MC74VHCT257A is an advanced high speed CMOS quad  
2−channel multiplexer fabricated with silicon gate CMOS technology.  
It achieves high speed operation similar to equivalent Bipolar  
Schottky TTL while maintaining CMOS low power dissipation.  
It consists of four 2−input digital multiplexers with common  
select (S) and enable (OE) inputs. When (OE) is held High, selection  
of data is inhibited and all the outputs go Low.

MARKING  
DIAGRAMS  
The select decoding determines whether the A or B inputs get routed  
to the corresponding Y outputs.  
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 VHCT257A 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 V = 0 V. These

CC  
input and output structures help prevent device destruction caused by  
supply voltage−input/output voltage mismatch, battery backup, hot  
insertion, etc.  
The internal circuit is composed of three stages, including a buffered  
output which provides high noise immunity and stable output. The  
inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V  
systems to 3.0 V systems.
