age. This device can be used to interface 5V to 3V systems

and two supply systems such as battery back up. This cir-

cuit prevents device destruction due to mismatched supply

and input voltages.

General Description

The VHC139 is an advanced high speed CMOS Dual 2-to-

Decoder/Demultiplexer fabricated with silicon gate

CMOS technology. It achieves the high speed operation

similar to equivalent Bipolar Schottky TTL while maintain-

ing the CMOS low power dissipation.

Features

■ High Speed: t_PD= 5.0 ns (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.)

The active LOW enable input can be used for gating or it

can be used as a data input for demultiplexing applications.

When the enable input is held HIGH, all four outputs are

fixed at a HIGH logic level independent of the other inputs.

An input protection circuit ensures that 0V to 7V can be

applied to the input pins without regard to the supply volt-

■ Power down protection is provided on all inputs

■ Pin and function compatible with 74HC139
