Hello, I was wondering if there is such a thing as a 16 to 1
multiplexer. I need something that can connect 16 individual inputs to
1 output 1 at a time in sequence. But I'm having trouble finding a
16:1 MUX. Also, I ordered some chips from mouser, and some are big
enough to stick in my bredboard but a lot of them were real tiny...
does anyone know what's up with the real tiny ones? I couldn't find in
the name of the chip something that would let me know that it was going
to be too tiny to fit in a regular solderless breadboard.
thanks |

Analog or digital? Motorola has a 16 channel analog mux, MC14067B.
Looks like Mouser has some.

If you cant find a 16:1 in a direct package, you can use smaller muxes
to build it. I know you can use some 2:1 or 4:1 muxes to build a 16:1.
Its an option if you can't find a dedicated 16:1.

You want to look for a DIP package. Anything with "SO" in the
description of the package is out.
"What's up" is that the smaller ones, called "surface mount", are
desirable because of size, take up only one side of the board, don't
require holes to be drilled, and are easier to place by machine. |
