In a multiplexer, can you direct the input into all the outputs at the same time?


I need to direct a single line into multiple outputs, so I'm using a MUX to direct the input into the desired outputs (one at a time). However if i ever wanted to do a broadcast to all my output lines at the same time, is there any MUX which allows it ? Can I connect the input to ALL the outputs directly? Thanks in advance



Answer



The functionality you appear to require appears to be serviced by what is called a cross-point switch. Usually they have several inputs and several outputs that form an open matrix. Loading a specific code word can connect one input to several outputs simultaneously. They are rarer than multiplexers but they do exist.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
