DESCRIPTION

The 74VHC139 is an advanced high-speed

CMOS DUAL 2 TO 4 LINE DECODER/

DEMULTIPLEXER fabricated with sub-micron

silicon gate and double-layer metal wiring C2MOS

technology.

The active l ow enable input can be used for gating

or as a data input for demultiplexing applications.

Whi le the enabl e input is held high, all four out puts

are high independently of the other inputs.

Power down protection is provided on all inputs

and 0 to 7V can be accepted on inputs with no

regard to the supply voltage. This device can be

used to interface 5V to 3V.

All inputs and outputs are equipped with

protection circui ts aga inst static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
