    Hi Ryan,

    These devices are the same pinout and same package. 

    Major difference is that the static voltage offset is on A-side for TCA9509

    For TCA9617, static voltage offset is on B-side. 

    TCA9509 TCA9617B
    VCCA 0.9V to 5.5V (1) 0.8V to VCCB
    VCCB 2.7V to 5.5V 2.2V to 5.5V
    SVO A-side B-side
    VILC (A-side for TCA9509), VIL (B-side for TCA9617B) 150 mV (typ) VILB = 0.4V
    Frequency 400kHz 1 MHz
    IOLA 10 uA 30 mA

    IOLB

    		 6mA 30 mA

    Buffered pF A-side

    		 1 mA = ~ 150Pf depending on data rate 550pF

    Buffer pF B-side

    		 400pF 550pF

    (1) Low-level supply voltage

    The rest of the specifications are characterized according to the I2C standard for standard mode, fast mode, and fast mode+ (TCA9617B only). Things like prop delay, and other timing specs will adhere to the I2C standard. 

    Regards,
