Product Introduction

CLM3485 is an RS-485 transceiver with a 3.0V~5.5V wide power supply, a bus port ESD level of 15KV HBM or above, a bus withstand voltage range of ± 15V, half duplex, low power consumption, and fully functional compliance with TIA/EIA-485 standards. CLM3485 includes a driver and a receiver, both of which can be independently enabled and disabled. When both are disabled, both the driver and receiver output a high resistance state. CLM3485 has a 1/8 load and allows 256 CLM3485 transceivers to be connected together on the same communication bus. Can achieve error free data transmission up to 12Mbps. The working voltage range of CLM3485 is 3.0~5.5 V, and it has functions such as fail safe, current limiting protection, overvoltage protection, etc. The product directly replaces international similar products with PIN, without the need to change the circuit board or system software, achieving complete replacement compatibility. Chiplon Microelectronics has developed its own testing plan to ensure that the factory products meet or even exceed the original specifications, supporting industrial grade (-40℃ ~ 85℃) working temperatures.
