The CD4051BM96 is a single-channel 8-to-1 analog multiplexer and demultiplexer from Texas Instruments in a 16-pin SOIC package. It operates from a 3 V to 20 V single supply or +/-2.5 V to +/-9 V dual supplies, with a 240 Ohm channel on-resistance and a 60 ns propagation delay. Quiescent current is 80 nA and bandwidth is 20 MHz. The device is non-inverting and operates across -55 C to +125 C.

The CD4051 is one of the longest-serving CMOS analog multiplexers, used to share a single ADC input across eight sensor channels, to switch audio and instrumentation signals, to select gain-setting resistors, and to expand microcontroller analog inputs. Its distinguishing capability is the 20 V supply range with level-shifted digital control, which lets 3.3 V or 5 V logic switch analog signals spanning a much wider rail than the logic itself. Industrial control, instrumentation, audio and data acquisition designers are the usual buyers. The 240 Ohm on-resistance means the driven load should be high-impedance or the source resistance accounted for in the error budget.
