CMOS Analog Multiplexers/Demultiplexers
with Logic Level Conversion

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 20V P-P can be achieved by digital
signal amplitudes of 4.5V to 20V (if V DD -V SS = 3V, a
V DD -V EE of up to 13V can be controlled; for V DD -V EE level
differences above 13V, a V DD -V SS of at least 4.5V is
required). For example, if V DD = +4.5V, V SS = 0V, and
V EE = -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 V DD -V SS and V DD -V EE 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
