4067 Analog Mux/DemuxCD4067B 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 74HC4067; 74HCT4067 is a single-pole 16-throw analog switch (SP16T) suitable foruse in analog or digital 16:1 multiplexer/demultiplexer applications.

four digital select inputs (S0, S1, S2 and S3), sixteen independent inputs/outputs (Yn), a
common input/output (Z) and a digital enable input (E). When E is HIGH, the switches are
turned off. Inputs include clamp diodes. This enables the use of current limiting resistors
to interface inputs to voltages in excess of VCC.
