How to change the number of output nodes in a multiplexer to increase the input voltage?
I want to use a 20 FET MOSFET multiplexer in the schematic shown below to handle a 12V, 220 mA output. The problem is the output current is too high for this multiplexer.
How can I change this multiplexer to output a smaller current at a higher voltage?
A:
The npn BJT needs to be able to sink 12v at 60mA.
If you put 1uF in parallel with the BJT base-emitter it would probably do the job.
It would not do this because at this level of loading, the BJT acts like a much bigger diode.
