The CD4051B, CD4052B, and CD4053B analog multiplexers are digitally-controlled analog switches having low ON impedance and very low OFF leakage current. Control of analog signals up to 20VP-P can be achieved by digital signal amplitudes of 4.5V to 20V (if VDD–VSS = 3V, a VDD–VEE of up to 13V can be controlled; for VDD–VEE level differences above 13V, a VDD–VSS of at least 4.5V is required). For example, if VDD = +4.5V, VSS = 0V, and VEE = –13.5V, analog signals from –13.5V to +4.5V can be controlled by digital inputs of 0V to 5V. These multiplexer circuits dissipate extremely low quiescent power over the full VDD–VSS and VDD–VEE supply-voltage ranges, independent of the logic state of the control signals.
