SLLSFR9A April 2024 – April 2024 THVD4411
PRODUCTION DATA
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.
The device has SLR pin which allows it to be used for two different maximum speed settings for RS-232 and for RS-485. This is beneficial as customers can qualify one device and use it in two separate end-applications. The devices also have flexible I/O supply pin VIO which enables digital interface voltage range, from 1.65V to 5.5V, different from bus voltage supply 3V to 5.5V.
