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.
