10.2.1 Design Requirements

The RXD output structure is an open-drain output stage which allows the TLIN2021-Q1 to be used with 3.3-V and 5-V controllers. If the RXD pin of the controller does not have an integrated pull-up, an external pull-up resistor to the controllers IO voltage is required. The external pull-up resistor value should be between 1 kΩ to 10 kΩ. The VSUP pin of the device should be decoupled with a 100-nF capacitor by placing it close to the VSUP supply pin. The system should include additional decoupling on the VSUP line as needed per the application requirements.
