Functional Description:

TD041S485H is a half-duplex enhanced transceiver designed for RS–485 data bus networks, which is fully compliant with TIA/EIA-485Astandardand is suitable for data transmission of up to 20Mbps. Their logic side supports 3.3V and 5V logic level conversion. Receivers have anexceptionallyhigh 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 ESDdesign. TheESDprotection level of A,B pin can be up to 15KV (Human Body Model).
