CLM485 is a low-power transceiver used for RS-485 and RS-422 communication, with each device having a driver and a receiver. The drive swing rate of CLM485 is not limited and can achieve a maximum transmission rate of 2.5Mbps. The driver has a short-circuit current limit and can be set to a high resistance state through a thermal shutdown circuit to prevent excessive power loss. The receiver input has a failure protection feature, which ensures a high-level output of logic when the input is open circuit. 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.
