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 V

= 0 V. These

input and output structures help prevent device destruction caused by

supply voltage

−

input/output voltage mismatch, battery backup, hot

insertion, etc.
