Product Summary

The SN65HVD12D transceiver combines a 3-state differential line driver and differential input line receiver that operate with a single 3.3-V power supply. It is designed for balanced transmission lines and meet or exceed ANSI standard TIA/EIA-485-A and ISO 8482:1993. The SN65HVD12D is a monolithic integrated circuit designed for bidirectional data communication on multipoint bus-transmission lines. The SN65HVD12D has active-high and active-low enables respectively, that can be externally connected together to function as direction control. Very low device standby supply current can be achieved by disabling the driver and the receiver.
