Future Electronics Offers the XR307xX Series of High Reliability Transceivers from Exar

Future Electronics, a global leading distributor of electronic components, announces availability of Exar’s XR307xX series of high reliability transceivers.

Pointe Claire, Canada, May 07, 2014 --( Future Electronics, a global leading distributor of electronic components, announces immediate availability of Exar's XR307xX series of high reliability transceivers.

The XR307xX series 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 ±15kV. 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 (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 XR3070- 75X drivers are slew limited for reduced EMI and error-free communication over long or unterminated data cables.

The devices with DE and RE pins include hot swap circuitry to prevent false transitions on the bus during powerup or live insertion, and can enter a 1nA low current shutdown mode for extreme power savings.

The transceivers draw less than 600μA from a +3.3V supply, and typically only 300μA when idling with the receivers active.

Typical applications include motor control, security systems, building and process automation, remote utility meter reading, energy monitoring and control, and long or unterminated transmission lines.
