1. Describe

SP3495EEN-L transceiver is suitable for For high-speed bidirectional communication Multipoint bus transmission line. they are designed for balanced data transfer and complies with both RS-485 and RS-422 EIA standards. per device Contains a differential driver and a differential recipient Driver differential output and receiver differential Inputs are connected internally to form half duplex Input/output to RS-485 bus. Separate RE and DE Pins enable and disable drivers and receivers independent or external together as a direct control. The device goes into low If both the driver and receiver are in power-down mode disabled. Disabled or powered bus pin output The lower device is in a high impedance state. High Impedance driver output remains across the The common mode voltage range is -7V to +12V. SP3495E - SP3497E operates from a single 3.3V power supply. SP3495E - SP3497E Transceiver Load Data bus is half of standard RS-485 unit load. This allows up to 64 devices Simultaneous connections on the bus do not violate RS-485 signal margin required but not used repeater. caused by excessive power consumption bus contention or by shorting the output to ground or Protection against voltage sources by short-circuit protection and thermal shutdown. This feature forces the driver If the absolute value is output to a high impedance state output current exceeds 250mA or if the junction The temperature exceeds 165°C. The receiver will be failsafe If the input is in a logic high output state Not connected (floating) or shorted. All RS-485 inputs and outputs are ESD protected up to +/-15kV body model.
