HI,

For TCA9543A , we can not find VOH/VOL, only find the VIH/VIL .

Please help to check it, thx

    This device is a passive switch. VOL is specified only for the SDA and /INT pins (as test condition for IOL).

    When the input signal is high, the switch is open, and the output voltage is determined by the pull-up resistor. When the input signal is low, the switch is closed, and the output voltage is the input voltage plus the voltage drop over the switch, which is RON × I; the current through the switch depends on the pull-up resistor.
