I need to find some i.c that allow to switch 30V to 8 outputs by the control of MCU (in fact 1 to 8 analog demultiplexer).
Do you know some i.c that works with this voltage?

This is the scheme for example:

How much current does the 30V out of the multiplexer have to supply? Is it always 30 volts of is it a signal that ranges up to 30 volts? (In other words is it good enough to switch 30V to one of the eight outputs based on the 3 bit input?)

It is a low current (some milli amperes). the voltage in the input is constant 30V DC.
