TCA6416A: TCA6416A I/O pin resistor value

Part Number: TCA6416A

What is the I/O pin pull down resistor value that can be used for TCA6416A is we are trying to ground it? (Vcc=3.3V)

  • Hello Bless Matz,

    Are you asking the minimum resistance if the device is being used as an output logic high or as an input?

    If an input, then it does not matter.

    If an output, the absolute maximum current allowed through a P Port is 50mA though we would recommend 10mA. At 3.3V the minimum recommended would be 330 ohms while the absolute minimum would be 66 ohms.

    Thanks,
