3 Description

The CD405xB analog multiplexers and demuliplexers

are digitally-controlled analog switches having low

ON impedance and very low OFF leakage current.

These multiplexer circuits dissipate extremely low

quiescent power over the full VDD – VSS and VDD –

VEE supply-voltage ranges, independent of the logic

state of the control signals.
