8-bit 2-to-1 multiplexer IC

Recommended Posts

I'd like to find an IC that will multiplex two 8-bit (i.e. 8-wire) signals, selecting one as output (on 8 wires). Does such an item exist? I'm not sure whether I'm searching for the right thing, but all I've been able to find is this TI 'LAN switch' which appears to do what I'm after, but doesn't seem to be breadboard-able. I could of course recreate the logic myself, using ICs with multiple 1-bit 2-to-1 multiplexers, but the wiring would be much less fun.

if you wish to minimize hand wiring & are using veroboad or single sided pcb.....

a pair of 'hc541.  one on the left, one on the right.

BUT the one on the right is upside down; why? 

so that you can do straight-through wiring on the output lines

    (so  left p18 to right p11.    left p17 to right p12.   ..etc..   left p11 to right p18)

 and then select via the output enables on pins 1 and 19.

8 inputs |   |   8 outputs   |   |

         |   |    3-state    |   |  8 inputs

                             | o |
