SN65LVCP114: SN65LVCP114 P/N Pair Inversion

user1359349

Part Number: SN65LVCP114

because the P/N of SN65LVCP114 can be swap,so,i want to know whether the P/N of Aout side and Bout side need to be swap at the same time if Cin was swap

if i configure the register through I2C interface?

thanks!

Greetings,

Yes you can switch polarity through I2C registers. Please note register 0x10 and 0x11.

hello

i have switched the P/N of input,but didn't switch the output,is that OK?

for the configuration,i reserved I2C interface and GPIO,choose one according to the need,if there is pull up resistor in chip,i have added a pull down resistor on the schematic,but don't install it on the PCB.

please check it for me ,thanks.

Greetings,

This is application or protocol dependent. But normally if you switch input polarity, you should also switch output as well.

If you have already done your pcb and input and output polarity are reversed, then through the register you can change output polarity - if needed.
