DESCRIPTION
The 74VHC139 is an advanced high-speed
CMOS DUAL 2 TO 4 LINE DECODER/
DEMULTIPLEXER fabricated with sub-micron

gating or as a data input for demultiplexing
applications. While 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 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 circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
