CD4052BE

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). 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. When a logic “1” is present at the inhibit input terminal, all channels are off. The CD4051B is a single 8-Channel multiplexer having three binary control inputs, A, B, and C, and an inhibit input. The three binary signals select 1 of 8 channels to be turned on, and connect one of the 8 inputs to the output. The CD4052B is a differential 4-Channel multiplexer having two binary control inputs, A and B, and an inhibit input. The two binary input signals select 1 of 4 pairs of channels to be turned on and connect the analog inputs to the outputs. The CD4053B is a triple 2-Channel multiplexer having three separate digital control inputs, A, B, and C, and an inhibit input. Each control input selects one of a pair of channels which are connected in a single-pole, double-throw configuration. When these devices are used as demultiplexers, the “CHANNEL IN/OUT” terminals are the outputs and the “COMMON OUT/IN” terminals are the inputs.
