Part Number: TCA9535
Other Parts Discussed in Thread: TCA8418, TCA8418E, TCA6418E

Hi we have using TCA9535PWR (TSSOP) I2C I/O Expander chip and speed is 400KHz.

we plan to increase I2C communication speed and chip package/footprint should be same (pin to pin compatible) as TCA9535PWR ,

Please suggest suitable part with high speed I2C communication.

Thanks 

Rajan

    Hey Rajan,

    Unfortunately, we do not have many 1MHZ I/O expanders that are going to be pin to pin with the TCA9535.

    The devices that do support 1MHz (not pin to pin) are the TCA6418E, TCA8418, and TCA8418E.

    Thanks,
    -Bobby
