Does it work if REF200A connects to Analog switch ?

Other Parts Discussed in Thread: TS5A3153

Dear all ,

  I'd like to force a constant current ( TI REF200A ) through analog switch (TS5A3153) go to a CMOS I/O pin.

My purpose is to measure voltage over protection diodes in CMOS device . That is for open short test .

Do you expect it works ?

Thank you very much !!!
