THVD4411 is a highly integrated and robust multiprotocol transceiver supporting RS-232, RS-422 and RS-485 physical layers. The device has one transmitter and one receiver to enable 1T1R RS-232 port. Device also integrates one transmitter and one receiver to enable half and full duplex RS-485 port. MODE selection pins enable shared bus and logic pins for the protocols to share a common single connector. Integrated termination for RS-485 bus pins and for RS-232 receiver inputs are provided so no external components are needed to realize a fully-functional communication port. These devices have slew rate select feature that enables them to be used at two maximum speeds based on the SLR pin setting.
These devices feature integrated Level 4 IEC ESD protection, eliminating the need for external system-level protection components. In addition, the RS-485 receiver fail-safe feature drives logic high on received logic output when the bus inputs are open or shorted together or when the bus is idle. Shutdown mode consumes ultra-low current (10µA typical) in power-sensitive applications. The device needs 3V to 5.5V supply that powers the charge pump for RS-232 and the drivers and receivers for both RS-232 and RS-485. A separate logic supply VIO (1.65V to 5.5V) enables interface with low level microcontrollers.
