AUGUST 2011 XR5486E-5488E ULTRA HIGH SPEED RS-485/RS-422 PROFIBUS TRANSCEIVERS WITH 1/8TH UNIT LOAD AND +/-15KV ESD-PROTECTION The XR5486E-XR5488E family of RS-485 devices are designed for reliable, bidirectional communication on multipoint bus transmission lines. Each device contains one differential driver and one differential receiver. XR5488E is a half-duplex device while the other part numbers are full-duplex. All devices comply with TIA/EIA-485 and TIA/EIA-422 standards. Leadfree and RoHS compliant packages are available for all models. These devices are 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 left un-driven or shorted. All RS485 bus-pins are protected against severe ESD events up to +/-15kV Air-Gap IEC-61000-4-2 , up to +/-8kV Contact Discharge IEC-61000-4-2 and 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°C to +85°C operating temperatures. Receivers have exceptionally high input impedance, which places only 1/8th the standard load on a bus. Up to 256 transceivers may coexist while preserving full signal margin. All devices operate from a single 5.0V power supply and draw negligible quiescent power. All versions except the XR5487E may independently enable and disable their driver and receiver and enter a low power shutdown mode if both driver and receiver are disabled. All outputs maintain high impedance in shutdown or when powered-off. • 5.0V Single Supply Operation • High Speed up to 52Mbps • Advanced Fail-safe Receiver Inputs • Hot Swap glitch protection on control inputs • Robust ESD Protection for RS-485 pins • +/-15kV Air-Gap Discharge • +/-15kV Human Body Model • +/-8kV Contact Discharge • 1/8th Unit Load, 256 transceivers on bus • Driver short circuit current limit and thermal shutdown for overload protection • Low Current 1uA shutdown mode except XR5487E • Industry standard package footprints • Motor Control • Building Automation • Security Systems • Remote Utility Meter Reading FIGURE TYPICAL APPLICATION CIRCUIT XR5488E STUB A XR5488E XR5488E RE DE RE DE Exar Corporation 48720 Kato Road, Fremont CA, 94538 • 510 668-7000 • FAX 510 668-7017 • XR5486E-5488E ULTRA HIGH SPEED RS-485/RS-422 PROFIBUS TRANSCEIVERS WITH 1/8TH UNIT LOAD AND +/-15KV ESD-PROTECTION FIGURE PIN OUT ASSIGNMENT RO 1 RE 2 DE 3 DI 4 8-Pin NSOIC Half Duplex XR5488E 8 VCC 7B 6A 5 GND VCC 1 RO 2 DI 3 GND 4 8-Pin NSOIC Full Duplex XR5487E 8A 7B 6Z 5Y NC 1 RO 2 RE 3 DE 4 DI 5 GND 6 GND 7 14-Pin NSOIC Full Duplex XR5486E 14 VCC 13 NC 12 A 11 B 10 Z 9Y 8 NC ORDERING INFORMATION PART NUMBER XR5486EID-F XR5487EID-F XR5488EID-F PACKAGE 14-pin Narrow SOIC 8-pin Narrow SOIC 8-pin Narrow SOIC OPERATING TEMPERATURE RANGE -40°C to +85°C -40°C to +85°C -40°C to +85°C DEVICE STATUS Active Note To order Tape and Reel option include "/TR" in ordering part number.

Receiver Output. When RE is low and if A-

O B -50mV, RO is High. If A-B -200mV,

RO is Low.

Receiver Output Enable. When RE is Low,

RO is enabled. When RE is High, RO is

I high impedance. RE should be High and DE
should be low to enter shutdown mode. RE
is a hot-swap input.

Driver Output Enable. When DE is High,
outputs are enabled. When DE is low, out-

I puts are high impedance. DE should be low
and RE should be High to enter shutdown
mode. DE is a hot-swap input.

Driver Input. With DE high, a low level on DI
forces Non-Inverting output low and invert-

I ing output high. Similarly, a high level on DI
forces Non-Inverting output High and Invert-
ing output Low.
