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 of the 74LCX139 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 of the 74LCX139 are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
