Description

The 74VHCT139A is an advanced high-speed CMOS DUAL 2 TO 4 LINE DECODER/ DEMULTIPLEXER fabricated with sub-micron silicon gate and double-layermetal wiring C2 MOS 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.

Power down protection of the 74VHCT139A 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 interface 5V to 3V.

All inputs and outputs of the 74VHCT139A are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess
voltage.
