However, NVE recommends that all integrated circuits be handled with appropriate care to avoid damage. Damage caused by inappropriate handling or storage could range from performance degradation to complete failure. Narrow- and Wide-Body Pinout Differences The narrow-body version (IL3685-3E) is designed for application flexibility and minimum board area in densely-populated PCAs. The widebody version (IL3685E) has redundant ground pins for layout flexibility. The narrow-body version provides a separate isolated DE output (ISODE) and Transceiver Device Enable (XDE) input. ISODE follows the Device Enable input (DE). XDE can be used to enable and disable the transceiver from the bus side, or connected to ISODE to enable and disable the transceiver from the DE controller-side input. The narrow-body version also provides separate bus-side power supply and ground pins— VDD2X and GND2X for the transceiver module and VDD2I and GND2I for the isolation module. The supplies and grounds should be externally connected for normal operation, but they can be used separately for testing or troubleshooting. The wide-body version has internal connections between the isolated DE output and the Transceiver Device Enable input, and well as between the two bus-side power supplies. The ISODE output can be used in PROFIBUS applications where the state of the isolated drive enable node needs to be monitored, or for testing or troubleshooting. Dynamic Power Consumption IsoLoop Isolators achieve their low power consumption from the way they transmit data across the isolation barrier. By detecting the edge transitions of the input logic signal and converting these to narrow current pulses, a magnetic field is created around the GMR Wheatstone bridge. Depending on the direction of the magnetic field, the bridge causes the output comparator to switch following the input logic signal. Since the current pulses are narrow, about 2.5 ns, the power consumption is independent of mark-to-space ratio and solely dependent on frequency. This has obvious advantages over optocouplers, which have power consumption heavily dependent on frequency and time.

Power Supply Decoupling Both VDD1 and VDD2 must be bypassed with 47 nF ceramic capacitors. These should be placed as close as possible to VDD pins for proper operation. Additionally, VDD2 should be bypassed with a 10 µF tantalum capacitor. Maintaining Creepage Creepage distances are often critical in isolated circuits. In addition to meeting JEDEC standards, NVE isolator packages have unique creepage specifications. Standard pad libraries often extend under the package, compromising creepage and clearance. Similarly, ground planes, if used, should be spaced to avoid compromising clearance. Package drawings and recommended pad layouts are included in this datasheet. DC Correctness The IL3685 incorporates a patented refresh circuit to maintain the correct output state with respect to data input. At power up, the bus outputs will follow the Function Table shown on Page 1. The DE input should be held low during power-up to eliminate false drive data pulses from the bus. An external power supply monitor to minimize glitches caused by slow power-up and power-down transients is not required. 7 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 Phone: (952) 829-9217 Fax: (952) 829-9189 www.IsoLoop.com ©NVE Corporation IL3685 Electromagnetic Compatibility The IL3685 is fully compliant with generic EMC standards EN50081, EN50082-1 and the umbrella line-voltage standard for Information Technology Equipment (ITE) EN61000.

Driver Features The RS-485 driver has a differential output and delivers at least 2.1 V across a 54 Ω load. In addition, unlike most other transceivers, the IL3685 also meets stringent PROFIBUS standards for maximum differential output voltage. Drivers feature low propagation delay skew to maximize bit width and minimize EMI. Drivers have tri-state capability via the active-high DE input. Receiver Data Rate, Cables and Terminations PROFIBUS Type A bus cable is recommended for high transmission speeds (more than 500 Kbps). Type B should only be used at low baud rates and low requirements on the network distances. IL3685 transceivers are intended for networks up to 4,000 feet (1,200 m) with Type A bus cable and proper termination. The maximum data rate decreases as cable length increases. 9 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 Phone: (952) 829-9217 Fax: (952) 829-9189 www.IsoLoop.com ©NVE Corporation IL3685 Termination and Fail-Safe Biasing Internal Biasing Resistors “Fail-safe biasing” forces a logic high state on “R” in response to an open-circuit condition between the bus “A” and “B” lines, or when no drivers are active on the bus. IL3000-Series Isolated Transceivers include internal pull-up and pull-down resistors of approximately 30 kΩ in the receiver section (RFS-INT in Figure 2 below): 5V 30K RFS-INT A RT RT R RFS-EXT VDD RFS-EXT 30K RFS-INT B GND Figure 2. Termination and internal and external fail-safe biasing resistors. These internal resistors ensure fail-safe operation if there are no termination resistors and up to four RS-485 worst-case Unit Loads of 12 kΩ. Termination Resistors Termination resistors should be on both ends of the network to minimize reflections. Values should be selected to match cable impedance; 220 Ω resistors are typical for PROFIBUS. External Fail-Safe Biasing Resistors Termination resistors bring the differential voltage across the conductor pair close to zero with no active drivers. In this case, the idle bus is indeterminate and susceptible to noise. External fail-safe biasing resistors (labeled RFS-EXT in Figure 2) at one end of the bus ensure fail-safe operation with a terminated bus. Biasing should provide at least 200 mV across the conductor pair to meet the RS-485 input sensitivity specification. Fail-safe resistors of 390 Ω are common for PROFIBUS. They should be on only one node of the network. Using the same value for pull-up and pull-down biasing resistors maintains balance for positive- and negative going transitions. 10 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 Phone: (952) 829-9217 Fax: (952) 829-9189 www.IsoLoop.com ©NVE Corporation IL3685 Package Drawings 0.15" 16-pin SOIC Package (-3 suffix) Dimensions in inches (mm); scale = approx. 5X 0.013 (0.3) 0.020 (0.5) NOM 0.007 (0.2) 0.013 (0.3) 0.386 (9.8) 0.394 (10.0) Pin 1 identified by either an indent or a marked dot 0.016 (0.4) 0.050 (1.3) 0.055 (1.40) 0.062 (1.58) 0.054 (1.4) 0.072 (1.8) 0.150 (3.81) 0.157 (3.99) 0.049 (1.24) 0.051 (1.30) 0.228 (5.8) 0.244 (6.2) NOTE: Pin spacing is a BASIC dimension; tolerances do not accumulate 0.004 (0.1) 0.012 (0.3) 0.3" 16-pin SOIC Package (no suffix) Dimensions in inches (mm); scale = approx. 5X 0.033 (0.85)* 0.043 (1.10) 0.260 (6.60)* 0.280 (7.11) 0.013 (0.3) 0.020 (0.5) 0.007 (0.2) 0.013 (0.3) 0.397 (10.08) 0.413 (10.49) 0.017 (0.43)* 0.022 (0.56) 0.016 (0.4) 0.050 (1.3) 0.007 (0.18)* 0.010 (0.25) 0.092 (2.34) 0.105 (2.67) Pin 1 identified by either an indent or a marked dot 0.08 (2.0) 0.10 (2.5) 0.292 (7.42)* 0.299 (7.59) 0.049 (1.24) 0.051 (1.30) 0.394 (10.00) 0.419 (10.64) NOTE: Pin spacing is a BASIC dimension; tolerances do not accumulate *Specified for True 8™ package to guarantee 8 mm creepage per IEC 60601. 0.004 (0.1) 0.012 (0.3) 11 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 Phone: (952) 829-9217 Fax: (952) 829-9189 www.IsoLoop.com ©NVE Corporation IL3685 Recommended Pad Layouts 0.15" 16-pin SOIC Pad Layout Dimensions in inches (mm); scale = approx. 5X 0.160 (4.06) 0.050 (1.27) 0.020 (0.51) 16 PLCS 0.275 (6.99) 0.3" 16-pin SOIC Pad Layout Dimensions in inches (mm); scale = approx. 5X 0.317 (8.05) 0.050 (1.27) 0.020 (0.51) 16 PLCS 0.449 (11.40) 12 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 Phone: (952) 829-9217 Fax: (952) 829-9189 www.IsoLoop.com ©NVE Corporation IL3685 Ordering Information and Valid Part Numbers IL 36 85 -3 V E TR13 Valid Part Numbers IL3685E IL3685E TR13 IL3685-3E IL3685-3E TR13 Bulk Packaging Blank = Tube TR13 = 13'' Tape and Reel Package E = RoHS Compliant Isolation Grade Blank = 2.5 kV Isolation / 600 WV V = 6 kV Isolation / 1 kV WV IL3685VE IL3685VE TR13 Package Type Blank = 0.3'' SOIC -3 = 0.15'' SOIC Channel Configuration 85 = RS-485 Base Part Number 36 = 40 Mbps PROFIBUS Product Family IL = Isolators RoHS COMPLIANT 13 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 Phone: (952) 829-9217 Fax: (952) 829-9189 www.IsoLoop.com ©NVE Corporation IL3685 Revision History ISB-DS-001-IL3685-Q June 2015 ISB-DS-001-IL3685-P ISB-DS-001-IL3685-O Change • Increased V-Series isolation voltage to 6 kVrms. • Increased typ.
