I have been checking different supplier websites, and can't seem to find what I am looking for so I am wondering if it even exists or not.

I am looking for a 4x 2:1 MUX IC with 4 select lines. I am trying to create a design for remote control that doesn't require a microcontroller by daisy chaining 2:1's together as shown in the picture below. The digital inputs represent button presses on my RC. I have 8 buttons to work with on my transceiver module and by using two of the MUX's I am trying to get up to 16.

I looked into using 4:1's but I would be leaving one input line empty because I cannot use the case when SEL1 = 1 and SEL2 = 1 because I am daisy chaining them together.

If this isn't the best route to take, can you please share what you might do?

Simulation Example of what I am trying to do

  • \$\begingroup\$ MC140xx analog muxes; with ina/inb/out/select X 4, that's 16 pins; probably not; but a triple, yes. \$\endgroup\$ – analogsystemsrf May 14 '19 at 16:44

ADG734, 4 x 1:2 switch with 4 control lines Available at Digikey.com

4 Circuit IC Switch 2:1, 4.5Ohm, 20-TSSOP

1.8 V to 5.5 V Single Supply

or 2.5 V Dual Supply

2.5 On Resistance

0.5 On Resistance Flatness

100 pA Leakage Currents

19 ns Switching Times


MAX333 is another, less expensive choice, also at Digikey. Appears to need higher power supply (+/-5V, or 0/10V)
