SCM3402ASI Half-Duplex RS485/RS422 Transceiver Features          Package 3.3V voltages supply, half-duplex 1/8 Unit Load—Up to 256 Nodes on a Bus Driver short circuit protection Over temperature protection Low power consumption shutdown function Receiver open circuit expired protection Stronger anti-chirp capacity The in a sudden changing of the integration voltage boycotts function Communication Speed up to 12Mbps in an electrical noise environment Applications     Industrial automation Building automation Smart meter Long-distance signal interaction and transmission Product optional package: SOP-8, Screen Printing information please see "Ordering Information" Functional Description The SCM3402ASI is a 3.3V powered, half-duplex, low-power RS-485 transceiver that fully meets the requirements of the TIA/EIA-485 standard. The SCM3402ASI includes a driver and a receiver, both of which can be independently enabled and disabled. When both are disabled, both the driver and the receiver output a high-impedance state. The SCM3402ASI has a 1/8 load that allows 256 SCM3402ASI transceivers to be connected to the same communication bus. Error-free data transfer of up to 12Mbps is possible. The SCM3402ASI operates from a voltage range of 3.0 to 3.6 V and features fail-safe, over-temperature protection, current limit protection, and overvoltage protection.
