MC74VHCT138A
3−to−8 Line Decoder
The MC74VHCT138A is an advanced high speed CMOS 3−to−8
decoder fabricated with silicon gate CMOS technology. It achieves
high speed operation similar to equivalent Bipolar Schottky TTL
while maintaining CMOS low power dissipation.
When the device is enabled, three Binary Select inputs (A0 − A2)
determine which one of the outputs (Y0 − Y7) will go Low. When
enable input E3 is held Low or either E2 or E1 is held High, decoding
function is inhibited and all outputs go high. E3, E2, and E1 inputs are
provided to ease cascade connection and for use as an address decoder
for memory systems.
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 they
have full 5.0 V CMOS level output swings.
The VHCT138A 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 voltage − input/output voltage mismatch, battery backup, hot
insertion, etc.
