PCA9539: Reliability Issue

Ke Su

Part Number: PCA9539
Other Parts Discussed in Thread: TCA9539, TCA9539-Q1

Is PCA9539 commercial part? any automatic or EP part (higher reliability grade part) available? Could anyone share the Qual report for this part?

Thanks,

Hey Ke,

I would actually recommend the TCA line up for this device, particularly TCA9539 (we do have an automotive qualified version for this). The TCA line up fixes some of the bugs from the PCA line up, generally has wider Vcc acceptance ranges, is pin to pin with the PCA, and is more cost competitive.

Thanks,
