Their logic side supports 3.3V and 5V logic level conversion. Receivers have an exceptionally high input impedance, which places only 1/8 of the standard load on a shared bus and up to 256 transceivers . TD041S485H reliability design of A, B pin is emphasized, including driver output over current protection and enhanced ESD design. The ESD protection level of A,B pin can be up to 15KV (Human Body Model).

Detailed Description TD041S485H is an advanced RS-485 transceivers. They each contain one driver and one receiver. These devices feature a fail-safe circuitry that guarantees a high receiver output voltage when the receiver inputs are either open, shorted or when they are connected to a terminated transmission line with all drivers disabled. TD041S485H operates with a two power supply. Their logic side supports 3.3V and 5V logic level conversion. The whole machine can monitor the overall working state of the module and limit the output high current to prevent the bus from overload or short circuit...
