SIT487E is a RS-485 transceiver with 5V power supply, half duplex, low power consumption, and fully meet the requirements of TIA / EIA-485 standard. SIT487E 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. SIT3082E has 1/8 load, which allows 256 SIT487E transceivers to be connected to the same communication bus. It can realize error-free data transmission up to 250kbps. SIT487E has a working voltage range of 4. 5~5. 5 V, and has the functions of fail safe, over temperature protection, current-limiting protection, over-voltage protection, etc. SIT487E has excellent ESD release ability, HBM up to ±16kV, contact discharge ±15kV that meet IEC61000-4-2.
