SLLA628 September 2023 THVD1424
The THVD1424 has the option to have two different power supplies – one for the differential bus and one for the logic pins that communicate with a controller for the device. The VCC will accept a voltage of 3 V to 5.5 V for normal operation (this is the entire possible range of RS-485 applications) and its logic supply will accept from 1.65 V to 5.5 V (allowing for 1.8 V controller support). The device can be configured as a standard 3 V to 5.5 V device by shorting VCC and VIO together. So any typical RS-485 interface power supply scheme will work with the THVD1424.
