TD(H)541S485H-A DFN package isolated RS485 Transceiver Package 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(Except RXD)  High isolation to 3000VDC (TDH541S485H-A 5000VDC)  Bus-Pin ESD protection up to 15kV(HBM)  Baud rate up to 500kbps  >25kV/us CMTI  Automatic send and receive data function  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℃  Moisture Sensitivity Level (MSL) 3 Applications  Industrial Automation  Building Automation  Smart Electricity Meter  Remote Signal Interaction, Transmission Functional Description TD(H)541S485H-A 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 500kbps. In addition, the product features an automatic switching function, that no longer requires the need to pass through the node to send and receive control signals, which to a certain extent, reduces the design complexity. 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). 2021.07.14-A/0 Page 1 of 9 MORNSUN Guangzhou Science & Technology Co., Ltd. reserves the copyright and right of final interpretation PDF
