SP3081EEN-L

The SP3081EEN-L is an Advanced-Failsafe RS-485/RS-422 Transceiver designed for reliable, bidirectional communication on multipoint bus transmission lines. Each device contains one differential driver and one differential receiver. This device is ruggedized for use in harsh operating conditions over the entire common-mode voltage range from -7 to 12V. Receivers are specially designed to fail-safe to a logic high output state if the inputs are left un-driven or shorted. All RS-485 bus-pins are protected against severe ESD events up to ±15kV (air-gap and human body model) and up to ±8kV contact discharge. Drivers are protected from excess current flow caused by bus contention or output short-circuits by both an internal current limit and a thermal-overload shutdown. Receivers have exceptionally high input impedance, which places only 1/8th the standard load on a shared bus. Up to 256 transceivers may coexist while preserving full signal margin.
