74VHC138

3-to-8 Decoder/Demultiplexer

0V to 7V can be applied to the input pins without regard to

the supply voltage. This device can be used to interface 5V

to 3V systems and two supply systems such as battery

back up. This circuit prevents device destruction due to

mismatched supply and input voltages.

General Description

The VHC138 is an advanced high speed CMOS 3-to-8

decoder/demultiplexer fabricated with silicon gate CMOS

technology. It achieves the high speed operation similar to

equivalent Bipolar Schottky TTL while maintaining the

CMOS low power dissipation.

Features

When the device is enabled, 3 binary select inputs (A₀, A₁

and A₂) determine which one of the outputs (O₀–O₇) will go

LOW. When enable input E₃is held LOW or either E₁or E₂

■ High Speed: t_PD= 5.7ns (typ) at T_A= 25°C

■ Low power dissipation: I_CC= 4 µA (max.) at T_A= 25°C

■ High noise immunity: V_NIH= V_NIL= 28% V_CC(min.)

is held HIGH, decoding function is inhibited and all outputs

go HIGH. E₃, E₁and E₂inputs are provided to ease cas-

■ Power down protection provided on all inputs

■ Pin and function compatible with 74HC138

cade connection and for use as an address decoder for

memory systems. An input protection circuit ensures that
