Control of analog signals up to 15 Vp-p can be achieved by digital signal amplitudes of 3-15V. For example, if V DD = 5V, VSs = OV and V EE = -5V, analog signals from -5V+5V can be controlled by digital inputs of 0-5V. The 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 logical "1" is present at the inhibit input terminal all channels are "OFF." CD4051M/CD4051C 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 the input to the output. CD4052M/CD4052C 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 differential analog inputs to the differential outputs. CD4053M/CD4053C 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. Features Wide range of digital and analog signal levels: digital 3-15V, analog to 15 Vp-p Low "ON" resistance: 80£2 (typ) over entire 15 Vp-p signal-input range for V DD - V EE = 15V High "OFF" resistance: input leakage +10 p A (typ) at V r -V c : 10V Logic level conversion for digital addressing signals of 3-1 5V (V DD - V ss = 3-1 5V) to switch analog signals to 15 Vp-p (V DD - V EE =...
