SP4082E 5V RS-485/RS-422 Half-Duplex Transceiver

The SP4082E is designed for reliable, bidirectional communication on multipoint bus transmission lines. The device contains one differential driver and one differential receiver. It is a half-duplex de- vice. The device complys with TIA/EIA-485 and TIA/EIA-422 standards. Lead-free and RoHS compli- ant packages are available. This device is ruggedized for use in harsh operating conditions over the entire common-mode volt- age range from -7V to +2V. Receivers are specially designed to fail-safe to a logic high output state if the inputs are un-driven or shorted. All RS-485 bus-pins are protected against severe ESD events up to ±15kV (Human Body Model). 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. Devices are rated for industrial (-40 to +85oC) operating temperatures. Receivers have exceptionally high input impedance, which places only /8th the standard load on a shared bus. Up to 256 transceivers may coexist while preserving full signal margin.
