TCA9617A: VCCA voltage and VCCB voltage

Part Number: TCA9617A
Other Parts Discussed in Thread: TCA9617B

Hi Team,

In TCA9617A/B, if VCCA supply voltage must <  VCCB supply voltage?

What's the difference with TCA9617A and TCA9617B?

Thank you.

  • Hi Lilian,

    The B version is designed so that the I2C bus is high-impedance when powered off, so it is recommended over the A version of the device. Both versions require that VCCA be less than or equal to VCCB. Please let me know if you have any further questions.

    Regards,
