PCA9306-Q1: the value of OFF-state resistance of SW

Other Parts Discussed in Thread: PCA9306

Dear all,

Could you teach me the minimum value of OFF-state resistance of SW at recommended operating range?

Because of the resistance of OFF-state, the rough value is OK.

For example, it is ○○V or more.

Best regards,

    Yamamoto-san,

    Since the PCA9306's SDA and SCL lines DO NOT rely on power being supplied to the VREF2 and VREF1 pins, the resistance of the switch when EN is low will be the same whether VREF2 and VREF1 is high or not.

    The value should be fairly large, but will vary from device to device. Typically on the order of 1M or more when EN is low.
