Parameter Rating Storage Temperature (TST) Range −65°C to +150°C Ambient Operating Temperature (TA) Range −40°C to +105°C Supply Voltages (VDD1, VDD2) −0.5 V to +7.0 V Input Voltages (VIA, VIB)1 −0.5 V to VDDI + 0.5 V Output Voltages (VOA, VOB)1 −0.5 V to VDDO + 0.5 V Average Output Current per Pin2 Side 1 (IO1) −10 mA to +10 mA Side 2 (IO2) −10 mA to +10 mA Common-Mode Transients3 −100 kV/µs to +100 kV/µs 1 VDDI and VDDO refer to the supply voltages on the input and output sides of a given channel, respectively. See the Printed Circuit Board Layout section. 2 See Figure 3 for maximum rated current values for various temperatures. 3 Refers to common-mode transients across the insulation barrier. Common- mode transients exceeding the absolute maximum ratings may cause latch- up or permanent damage. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ESD CAUTION Table 18. Maximum Continuous Working Voltage1 Parameter Max Unit Constraint AC Voltage, Bipolar Waveform 300 V rms 50-year minimum lifetime DC Voltage 300 V dc 50-year minimum lifetime 1 Refers to continuous voltage magnitude imposed across the isolation barrier. See the Insulation Lifetime section for more details. Table 19.
