Hi Team,

I have a question about TS5A23159, can TS5A23159 replace FSA2257? Here are some information about FSA2257. FSA2257 is one of chips in Fairchild.

    Hi Gust,

    The TS5A23159 can be used as a replacement for the FSA2257 and has similar or better performance, however it will not be a pin to pin replacement as the pinouts are different between the devices and package options.

    If you need better leakage performance, I would also recommend looking at the TMUX1136 which is also a 2:1, 2 channel multiplexer with a slightly higher RON (2 ohms), but considerably lower leakage currents (3pA typical vs. 2nA typical).

    Thanks!
