Hi team,

What's the difference between LSF0102 and LSF0108 in addition to channel numbers? 

Tool/software:

Hi team,

Recently we are using LSF0108 with our on-board xds110(3V3) to get a 5V SWD port.

XDS_VCC = 3.3V, XDS_VBUS = 5V

However in some cases the SWD comms will fail

1. example 1 - SWD is fine when using jumper to connect…

Hi,

What is the expected operation for the LSF0108 and other LSF translators if VREF_A is off (0V) and VREF_B & the EN pin are both at 3.3V? Would the B-side I/O be pulled down to GND, would the I/O be high impedance…

Hi teams,

I was wondering if the A port and B port are open drain or push pull? Since I saw in the data sheet mentioned that they can have both open-drain and push pull application.

Thanks for the help!
