Why is the PCA9555PW listed as EOL on Mouser, but Active on the TI site? Is it really still Active? Thank you, Bill

Bill,

It is technically still active, but we are trying to move customers to the TCA versions of all of our I2C devices. So the TCA9555 is what we'd recommend, as this is an updated version of the PCA9555 in a new design process.

Thank you Eric, this is very helpful. We use this part in many of our products. Are there any performance differences besides the supply voltage that we should be aware of?

Bill,

None that I'm aware of, but just in case I've notified our I2C expert to follow up.

Hi Bill,

There is an INT errata called out in the datasheet. Aside from that, there are some minor differences in electrical characteristics.
