Control of analog signals up to P-P can be achieved by digital signal amplitudes of. to (if - =, a - of up to can be controlled; for - level differences above, a - of at least. is required). For example, if = +., =, and = -., analog signals from -. to +. can be controlled by digital inputs of to. These multiplexer circuits dissipate extremely low quiescent power over the full - and - supply-voltage ranges, independent of the logic state of the control signals. When a logic is present at the inhibit input terminal, all channels are off. The CD is a single -Channel multiplexer having three binary control inputs,,, and C, and an inhibit input. The three binary signals select of channels to be turned on, and connect one of the inputs to the output. The CD is a differential -Channel multiplexer having two binary control inputs, and, and an inhibit input. The two binary input signals select of pairs of channels to be turned on and connect the analog inputs to the outputs. The CD is a triple -Channel multiplexer having three separate digital control inputs,,, 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 CHNNEL terminals are the outputs and the COMMON OUT/IN terminals are the inputs. Ordering Information PRT NUMER TEMP.
