Hi TI Guru,
I plan to use TCA9548A in my design however i have some doubt here, and my use case as below.
Master side (1.8V pull up), Slave side (3.3V pull up), VCC = 1.8V (Vpass about 1V from figure 14)
1. How the device do the translation since it is a passive switch, once the gate is on, master and slave will be connected. Hence, in my used case, the I2C line will be 3.3V once the gate is ON ?
2. Total capacitance for TCA9548A when all gate is on, Total Cap = 28+8*7.5 = 88pF, am i get it right? (I just need the calculation for TCA9548A only, i will add master and slave devices in my calculation)
3. Is the Pull up resistance calculation is parallel all the pull up resistor? ex. Master 10K, all Slave 10K, is it equivalent to pull up of 10K/9 ?
Thanks in advance
Best regards,
Alder
