Other Parts Discussed in Thread: PCA9555
Hi Team,
My customer are doing the interference test for the TCA9555. The procedure is as below:
1. power on the part and transmit the data between the MCU and TCA9555.
2. Use the 50MHz, sinusoidal wave to interfere the communication, and the link between the MCU and TCA9555 will be broken. the MUC can not identify the part.
And then, the output of the TCA9555 will be flip randomly. such as for logic 1 to logic 0.
So can you help to reply the question:
1. Does the behaver make sense?
2. How can our part to keep the same logic when the link is broken?
Lacey
Thanks a lot!
