DESCRIPTION
The M74HC139 is an high speed CMOS QUAD
2-INPUT NAND GATE fabricated with silicon gate
C 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.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
