SIT3485EESA

SIT3485E 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. SIT3485E 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. SIT3485E has 1/8 load, which allows 256 SIT3485E transceivers to be connected to the same communication bus. It can realize error- free data transmission up to 12Mbps. SIT3485E 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.
