Sit3485 is compatible with max3485, sp3485 and other models. Sit3485 is a 3.3V power supply, half duplex, low power consumption, fully meet the requirements of TIA / eia-485 standard RS485 transceiver chip. Sit3485 includes a driver and a receiver, both of which can be enabled and closed independently. When both are disabled, both the driver and receiver output high resistance state. Sit3485 has 1 / 8 load, which allows 256 sit3485 transceivers to be connected to the same communication bus. It can realize error free data transmission up to 12mbps. The operating voltage range of sit3485 is 3.0V ~ 3.6V. It has the functions of fail safe, over temperature protection, current limiting protection and over-voltage protection. Sit3485 pin to pin or partly better than max3485 and sp3485, with the following characteristics: 3.3V power supply, half duplex; 1 / 8 unit load, allowing up to 256 devices to be connected to the bus Driver short circuit output protection; Over temperature protection function; low power cut-off function; Receiver open circuit failure protection; It has strong anti noise ability; Integrated transient voltage rejection function: The data transmission rate can reach 12mbps in electric noise environment; Please download the specification in the navigation bar > > download the specification
