CLM3491 is an RS-485/RS-422 transceiver with a wide power supply range, full duplex, low power consumption, and fully meets the requirements of TIA/EIA-485 standards. CLM3491 includes a driver and a receiver, both of which can independently transmit signals. CLM3491 has a 1/8 load and allows 256 CLM3491 transceivers to be connected together on the same communication bus. Can achieve error free data transmission up to 12Mbps. The working voltage range of CLM3491 is 3.0V~5.5V, and it has functions such as fail safe, current limiting protection, and overvoltage protection. CLM3491 has excellent ESD release capability, with HBM reaching ± 15kV. 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 (0 ℃~70 ℃) working temperatures.
