Notes:
1. The TxD input is edge sensitive. Voltage magnitude of the input signal is specified, but edge rate specifications must also be met.
2. The maximum time allowed for a logic transition at the TxD input is 1 μs.
3. Uniform magnetic field applied across the pins of the device. Cross-axis multiplier effective when field is applied perpendicular to the pins.
4. If VDD2 falls below the specified failsafe supply voltage, RxD will go High.
Electrostatic Discharge Sensitivity
This product has been tested for electrostatic sensitivity to the limits stated in the specifications. 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.
Electromagnetic Compatibility
The IL41050 is fully compliant with generic EMC standards EN50081, EN50082-1 and the umbrella line-voltage standard for Information
Technology Equipment (ITE) EN61000. The IsoLoop Isolator’s Wheatstone bridge configuration and differential magnetic field signaling ensure
excellent EMC performance against all relevant standards. NVE conducted compliance tests in the categories below:
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)
Immunity to external magnetic fields is higher if the field direction is “end-to-end” (rather than to “pin-to-pin”) as shown in the
diagram at right.
