All transmit and receive channels operate at 110 Mbps over the full temperature and supply voltage range. The symmetric magnetic coupling barrier provides a typical propagation delay of only 10 ns and a pulse width distortion of 2 ns, achieving the best specifications of any isolator. Typical transient immunity of 30 kV/s is unsurpassed. Available in 0.15" SOIC packages, the four-channel devices provide the highest channel density available. Typical transient immunity of 30 kV/s is unsurpassed. High channel density makes these devices ideal for isolating ADCs and DACs, parallel buses and peripheral interfaces. The IL715, IL716, and IL717 are available in 0.3" and 0.15" 16-pin SOIC packages and performance is specified over the temperature range of -40C to +100C without derating. The IL715T, IL716T, and IL717T are specified over -40C to +125C; the widest temperature range digital couplers available.

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. Both power supplies to these devices should be decoupled with low ESR 47 nF ceramic capacitors. Ground planes for both GND1 and GND2 are highly recommended for data rates above 10 Mbps. Capacitors must be located as close as possible to the VDD pins. Signal Status on Start-up and Shut Down Electromagnetic Compatibility To minimize power dissipation, input signals are differentiated and then latched on the output side of the isolation barrier to reconstruct the signal. This could result in an ambiguous output state depending on power up, shutdown and power loss sequencing. Therefore, the designer should consider including an initialization signal in the start-up circuit. Initialization consists of toggling the input either high then low, or low then high. IsoLoop Isolators have the lowest EMC footprint of any isolation technology. IsoLoop Isolators' Wheatstone bridge configuration and differential magnetic field signaling ensure excellent EMC performance against all relevant standards. These isolators are fully compliant with generic EMC standards EN50081, EN50082-1 and the umbrella line-voltage standard for Information Technology Equipment (ITE) EN61000. NVE has completed compliance tests in the categories below: Data Transmission Rates The reliability of a transmission system is directly related to the accuracy and quality of the transmitted digital information. For a digital system, those parameters which determine the limits of the data transmission are pulse width distortion and propagation delay skew. EN50081-1 Residential, Commercial & Light Industrial Methods EN55022, EN55014 EN50082-2: Industrial Environment Methods EN61000-4-2 (ESD), EN61000-4-3 (Electromagnetic Field Immunity), EN61000-4-4 (Electrical Transient Immunity), EN61000-4-6 (RFI Immunity), EN61000-4-8 (Power Frequency Magnetic Field Immunity), EN61000-4-9 (Pulsed Magnetic Field), EN61000-4-10 (Damped Oscillatory Magnetic Field) ENV50204 Radiated Field from Digital Telephones (Immunity Test) Propagation delay is the time taken for the signal to travel through the device. This is usually different when sending a low-to-high than when sending a high-to-low signal. This difference, or error, is called pulse width distortion (PWD) and is usually in nanoseconds. It may also be expressed as a percentage: PWD% = Maximum Pulse Width Distortion (ns) Signal Pulse Width (ns) Immunity to external magnetic fields is even higher if the field direction is "end-to-end" rather than to "pin-to-pin" as shown in the diagram below: x 100% For example, with data rates of 12.5 Mbps: PWD% = 3 ns x 100% = 3.75% 80 ns This figure is almost three times better than any available optocoupler with the same temperature range, and two times better than any optocoupler regardless of published temperature range. IsoLoop isolators exceed the 10% maximum PWD recommended by PROFIBUS, and will run to nearly 35 Mb within the 10% limit. Cross-axis Field Direction Propagation delay skew is the signal propagation difference between two or more channels. This becomes significant in clocked systems because it is undesirable for the clock pulse to arrive before the data has settled. Short propagation delay skew is therefore especially critical in high data rate parallel systems for establishing and maintaining accuracy and repeatability. Worstcase channel-to-channel skew in an IL700 Isolator is only 3 ns, which is ten times better than any optocoupler. IL700 Isolators have a maximum propagation delay skew of 6 ns, which is five times better than any optocoupler. 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 mark-to-space ratio. 7 IL715/IL716/IL717 Application Diagrams Isolated Logic Level Shifters +5V +3.3V DO DI Sensor Controller ADC CLK CS IL717 GND 1 GND 2 Single-Channel Isolated Delta-Sigma A/D Converter Bridge Bias Delta Sigma A/D CS5532 Bridge + Bridge Isolation Boundary Serial Data Out Iso SD Out Serial Data In Iso SD In Data Clock Iso Data Clock Chip Select Iso CS IL717 Clock Generator OSC 2 This circuit illustrates a typical single-channel delta-sigma ADC. The A/D is located on the bridge with no signal conditioning electronics between the bridge sensor and the ADC. In this case, the IL717 is the best choice for isolation. It isolates the control bus from the microcontroller. The system clock is located on the isolated side of the system. 8 IL715/IL716/IL717 Package Drawings, Dimensions and Specifications 0.15" SOIC Package Dimensions in inches (mm) 0.152 (3.86) 0.157 (3.99) 0.013 (0.3) 0.020 (0.5) NOM 0.016 (0.4) 0.050 (1.3) 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 0.228 (5.8) 0.244 (6.2) 0.054 (1.4) 0.072 (1.8) 0.040 (1.02) 0.050 (1.27) 0.040 (1.0) NOTE: Pin spacing is a BASIC 0.060 (1.5) dimension; tolerances do not accumulate 0.004 (0.1) 0.012 (0.3) 0.3" SOIC Package Dimensions in inches (mm) 0.013 (0.3) 0.020 (0.5) 0.287 (7.29) 0.300 (7.62) 0.007 (0.2) 0.013 (0.3) 0.397 (10.1) 0.413 (10.5) Pin 1 identified by either an indent or a marked dot 0.394 (10.00) 0.419 (10.64) NOM 0.016 (0.4) 0.050 (1.3) 0.092 (2.34) 0.105 (2.67) 0.08 (2.0) 0.10 (2.5) 0.040 (1.0) NOTE: Pin spacing is a BASIC 0.060 (1.5) dimension; tolerances do not accumulate 9 0.004 (0.1) 0.012 (0.3) IL715/IL716/IL717 Ordering Information and Valid Part Numbers IL 716 T - 3 E TR13 Valid Part Numbers Bulk Packaging Blank = Tube TR7 = 7'' Tape and Reel TR13 = 13'' Tape and Reel Package Blank = 80/20 Tin/Lead Plating E = RoHS Compliant Package Type Blank = 0.30'' 16-pin SOIC -3 = 0.15'' 16-pin SOIC Grade Blank = Standard T = High Temperature Base Part Number 715 = 4 Drive Channels 716 = 2 Drive Channels 2 Receive Channels 717 = 3 Drive Channels 1 Receive Channel Product Family IL = Isolators RoHS COMPLIANT 10 IL715 IL715E IL715-3 IL715-3E IL715T IL715TE IL715T-3 IL715T-3E IL716 IL716E IL716-3 IL716-3E IL716T IL716TE IL716T-3 IL716T-3E IL717 IL717E IL717-3 IL717-3E IL717T IL717TE IL717T-3 IL717T-3E All IL715, IL716, and IL717 part types are available on tape and reel.
