TCA6408A / min/max rise time to VPOR

S.Satoshi

Please let me ask about min/max rise time to VPOR. I believe that the POR should be worked correctly if the VCC range and tFT in Table 10 are satisfied. Is my understanding correct?

Sonoki-San,

Yes, this is the correct sequence that must be followed in order to meet the acceptable POR requirements for proper operation.

HI Francis,

Please let me ask one more.

Can we start access via I2C in the immediate wake of reaching VPOR? Or is any delay time needed?

Best Regards,

Sonoki

Hello Sonoki-San,
There is essentially no delay after you have reached the VPOR level. This is very similar to tREC, which shows that it is 0nS.
