XR3070XED-F
DESCRIPTION
FEATURES
The XR3070-78X family of high performance RS-485/ 422 devices are designed for improved performance in noisy industrial environments and increased tolerance to system faults.
The analog bus pins can withstand direct shorts up to ±18V, and are protected against ESD events up to ±15k V. The differential high output driver delivers 10% higher SNR than standard RS-485/422 devices, affording additional noise margin or extended cable lengths.
The receivers include full fail-safe circuitry, guaranteeing a logic-high receiver output when the receiver inputs are open, shorted, or undriven. The receiver input impedance is at minimum 96k W (1/8 unit load), allowing up to 256 devices on the bus while preserving the full signal margin.
The drivers are protected by short circuit detection as well as thermal shutdown, and maintain high impedance in shutdown or when powered off. The XR307075X drivers are slew limited for reduced EMI and errorfree munication over long or...
