DESCRIPTION

The 74VHCT139A 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 low enable input can be used for gating

or as a data input for demultiplexing applications.

When the enable input is held high, all four outputs

are high independently of the other inputs.

Power down protection is provided on all inputs

and outputs 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 since all

inputs are equipped with TTL threshold.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
