HCF4097B, a analog multiplexer/demultiplexer CMOS, is a digitally controlled analog switches device having low ON impedance, low OFF leakage current and internal address decoding. in addition, the ON resistance is relatively constant over the full input-signal range.
HCF4097B is a differential 8-channel multiplexer having three binary control inputs A, B, C, and an inhibit input. The inputs permit selection of one of eight pairs of switches. A logic "1" present at the inhibit input turns all channels off.
