SP4082E

SP4082E 5V RS-485/RS-422 Transceivers 1/8th Unit Load, Slew-Rate Limited, ±15kV ESD-Protected FEATURES 5.0V single supply operation Receiver failsafe on open or shorted lines 1/8th Unit Load, 256 transceivers on bus Robust ESD protection for RS-485 pins ±15kV Human Body Model Controlled driver slew rates 115kbps, Low EMI Driver short circuit current limit and thermal shutdown for overload protection Industry www.DataSheet4U.com standard package footprints RO 1 RE 2 DE 3 DI 4 8 PIN NSOIC SP4082E Half Duplex 8 Vcc 7 B 6 A 5 GND APPLICATIONS Motor Control Building Automation Security Systems Remote Meter Reading Long or un-terminated transmission lines 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 device. The device complys with TIA/EIA-485 and TIA/EIA-422 standards. Lead-free and RoHS compliant packages are available. This device is ruggedized for use in harsh operating conditions over the entire common-mode voltage range from -7V to +12V. 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 shutdow...
