General Description
These analog multiplexers/demultiplexers are digitally con-
trolled analog switches having low ‘‘ON’’ impedance and
very low ‘‘OFF’’ leakage currents. Control of analog signals
an inhibit input. Each control input selects one of a pair of
channels which are connected in a single-pole double-throw
configuration.

CD4051BM/CD4051BC is a single 8-channel multiplexer
having three binary control inputs. A, B, and C, and an inhibit
