Other Parts Discussed in Thread: TCA6424A, PCA9534
Hi,
There are some questions of TCA9535 in Primax, could you please give some feedback? Thanks!
1) For example of PCA9534, suppose that all of IO pins (8 channel defined as input) change the status at same time, how it echo the changes? Parallel processing or distributed processing? ? TCA9535 and TCA6424A?
2) Suppose that IC are processing the interrupt event, there are some level shift at input Pin. How does the IC do? Lost the data?
3) What is Effective action of input pin (flip an IO? Or rising edge shift?)
4)What is max data rate of IO for PCA9534?
5) do there need some time if we write expander by I2C?
6) if we communicate with expander each 2mS, how much i2C communication rate(KHZ) is OK?
