SN65HVD11-HT High Temperature 3.3-V RS-485 Transceiver



High Temperature 3.3-V RS-485 Transceiver


The SN65HVD11 combines a 3-state differential line driver and differential input line receiver that operates with a single 3.3-V power supply.

It is designed for balanced transmission lines and meets or exceeds ANSI TIA/EIA-485-A and ISO 8482:1993, with the exception that the thermal shutdown is removed. This differential bus transceiver is a monolithic integrated circuit designed for bidirectional data communication on multipoint bus-transmission lines. The driver and receiver have active-high and active-low enables, respectively, that can be externally connected together to function as direction control.

The driver differential outputs and receiver differential inputs connect internally to form a differential input/ output (I/O) bus port that is designed to offer minimum loading to the bus when the driver is disabled or VCC = 0.
