Description
The 74LCX139 is a low voltage CMOS dual 2 to 4
line Decoder / Demultiplexer fabricated with sub-
micron silicon gate and double-layer metal wiring
C²MOS technology.
It is ideal for low power and high speed 3.3V
applications; it can be interfaced to 5V signal
environment for inputs.
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.
It has same speed performance at 3.3V than 5V
AC/ACT family, combined with a lower power
consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
