Product Summary
The CD4051BE is a CMOS Analog Multiplexers/Demultiplexer. The CD4051BE is digitally-controlled analog switche 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. The applications of the CD4051BE include Analog and Digital Multiplexing and Demultiplexing, A/D and D/A Conversion, Signal Gating.
