DETAILED DESCRIPTION The SP307XE family of high speed transceiv- ers for RS-485/RS-422 communication con- tain one driver and one receiver. These devices feature fail-safe circuitry, which guar- antees a logic-high receiver output when the receiver inputs are open or shorted, ...

After an ESD event, the SP3070E - SP3078E keep working without latchup or damage. ESD protection can be tested in various ways. The transmitter outputs and receiver inputs of the SP3070E - SP3078E are characterized ...
