LSF0204: Connecting two in series- one after the other

Pratheesh

Part Number: LSF0204

If we connect two LSF0204 back-to-back (in series), will there be any functional issues related to the direction sensing.

In my design, there is a module with LSF0204 used to translate 1.8V level to 3.3V level. I am planning to connect another LSF0204 to translate it to 5V level.

There is no direction sensing. The LSF is a passive switch; the switch closes when any I/O is low.

With multuple LSFes in series, all the pull-up resistors are in parallel, so the low-level voltage increases, depending on the drive strength of the other devices.

Okay.. That makes sense. Thanks a lot.
