DESCRIPTION

The M74HC139 is an high speed CMOS QUAD

2-INPUT NAND GATE fabricated with silicon gate

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.
