Digital Multiplexers

By allowing multiple inputs to be independently switched to a single output, digital multiplexers enable general purpose input expansion simplifying interface busses.

Digital multiplexers allow a number of inputs to be independently switched to a single output. NXP's digital multiplexers are available in multiple logic families with one digital output connecting to one of 2, 4 or 8 input lines based on the digital code present at control inputs. Some multiplexers also offer complimentary outputs.

Digital multiplexers are available in standard SO, TSSOP and innovative leadless DQFN packages for PCB space saving. NXP's digital multiplexers are fully specified from -40 ºC to 125 ºC.
