SIT3085E is a RS-485 transceiver with 5V power supply, half duplex, low power consumption, and fully meet the requirements of TIA/EIA-485 standard.  SIT3085E includes a driver and a receiver, both of which can be enabled and closed independently. When both are disabled, both the driver and the receiver output are high resistance state. SIT3085E has 1/8 load, which allows 256 SIT3085E transceivers to be connected to the same communication bus. It can realize error-free data transmission up to 1Mbps. SIT3085E has a working voltage range of 4. 5~5. 5V, and has the functions of fail-safe, overtemperature protection, current-limiting protection, over-voltage protection and hot-swap input control functions. SIT3085E has excellent ESD release ability, HBM up to ±16kV, contact discharge ±16kV that meet IEC61000-4-2
