DESCRIPTION
The 74VHC139 is an advanced high-speed
CMOS
DEMULTIPLEXER fabricated with sub-micron
silicon gate and double-layer metal wiring C
technology.
The active low enable input can be used for 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.

Table 1: Order Codes
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.
