data transmissionICinsulated

FEATURES Ultra-small, ultra-thin, chip scale DFN package Compliant with TIA/EIA-485A standard Integrated isolated 5V power I/O power supply range supports 3.3V and 5V microprocessors High isolation to 3000VDC (TDH541S485H 5000VDC) Bus-Pin ESD protection up to 15kV(HBM) Baud rate up to 1Mbps >25kV/us CMTI Low communication delay 1/8 unit load—up to 256 nodes on a bus Bus fail-safe Bus driver short circuit protection Industrial operating ambient temperature range: -40℃ to +105℃ Meet AEC-Q100 standards EN62368 approval Moisture Sensitivity Level MSL) 3 TD(H)541S485H is a half-duplex enhanced transceiver designed for RS–485 data bus networks, which is fully compliant with TIA/EIA-485A standard and is suitable for data transmission of up to 1 Mbps. 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. The reliability design of A and 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).
