SIT3088E is a RS-485 transceiver with 3.0V~5.5V wide power supply, bus port ESD protection capacity of over 15kV HBM, bus withstand voltage range of ±15V, half duplex, low power consumption, and fully meet the requirements of TIA / EIA-485 standard. SIT3088E 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. SIT3088E has 1/8 load, which allows 256 SIT3088E transceivers to be connected to the same communication bus. It can realize error-free data transmission up to 14Mbps. SIT3088E has a working voltage range of 3.0~5.5V, and has the functions of fail safe, over temperature protection, current-limiting protection, over-voltage protection, etc.
