10.1.1.2 Detailed Design Procedure

The RXD output structure is an open-drain output stage. This allows the SN65HVDA195-Q1 to be used with 3.3-V and 5-V I/O microcontrollers. If the RXD pin of the microcontroller does not have an integrated pullup, an external pullup resistor to the microcontroller I/O supply voltage is required.

The VSUP pin of the device should be decoupled with a 100-nF capacitor as close to the supply pin of the device as possible.

The NWAKE pin is a high voltage wake-up input to the device. If this pin is not being used it should be tied to VSUP.
