ISO7741: Does ISO7741DWR Pin3 have internal pull high to VCC ?

Part Number: ISO7741

Hi Team,

There is a good new that we DIN ISO7741DWR

If ISO7741DWR is used for signal primary & secondary side transmission !

Does Pin3 have internal pull high to VCC?
thanks

  • Hi Kygo,

    Thank you for posting and for sharing this good news! ISO7741DWR is a "default-HIGH output" device, so it has an internal pull-up resistor to help it maintain this state in the absence of any input signals as shown in the I/O schematic from the ISO774x datasheet (copied below):




    Please let us know if there are any additional questions. If a channel is not used on this device, we recommend connecting the input pin to Vcc externally through a pull up resistor of ~4.7kΩ and leaving the output pin floating or disconnected.


    Thank you!
