Applications
• Analog and Digital Multiplexing and Demultiplexing
• A/D and D/A Conversion
• Signal Gating
* When these devices are used as demultiplexers the “CHANNEL
IN/OUT” terminals are the outputs and the “COMMON OUT/IN” ter-
minals are the inputs.
Description
CD4067BMS and CD4097BMS CMOS analog multiplexers/
demultiplexers* are digitally controlled analog switches 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.
The CD4067BMS is a 16 channel multiplexer with four binary
control inputs, A, B, C, D and an inhibit input, arranged so that
any combination of the inputs selects one switch.
The CD4097BMS 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.
