DESCRIPTION

The M74HCT139 is an high speed CMOS DUAL

TWO LINE TO FOUR LINE DECODER/

DEMULTIPLEXER fabricated with silicon gate

C2MOS 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.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
