TCA9800: Application Usage Consult

Part Number: TCA9800

Hi Team,

Customer follows our D/S figure 20's typical application to verify the usage, but the supply voltage of A/B side are both 3.3V. They find our TCA9800 is not working normally. Are there any possible reasons behind this? Does supply voltage of VCCA is must larger than VCCB here? Thanks.

Best,

Stanley
