Other Parts Discussed in Thread: CD4051B

We are about to use CD4051B as de-multiplexer.

How much is the output current we can obtain?

The CD4051B itself does not actively drive its data pins.

You can get as much current as your other device can output, limited only by the switch resistance (see r_ON in the datasheet).
