DESCRIPTION
The 74VHCT139A is an advanced high-speed
CMOS
DUAL
2
TO
DEMULTIPLEXER fabricated with sub-micron
silicon gate and double-layermetal wiring C
2
MOS
technology.
The active low enable input can be used for
4
LINE
DECODER/
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 outputs and 0 to 7V can be accepted on
inputs with no regard to the supply voltage. This
device can be used to interface5V to 3V.
All
inputs
and
outputs are
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
