6 / 16 page 6 LT1787/LT1787HV 1787fc Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: ESD (Electrostatic Discharge) sensitive devices. Extensive use of ESD protection devices are used internal to the LT1787/LT1787HV, however, high electrostatic discharge can damage or degrade the device. Use proper ESD handling precautions. Note 3: The LT1787C/LT1787I are guaranteed functional over the operating temperature range of –40 °C to 85°C. The LT1787H is guaranteed functional over the operating temperature range of –40 °C to 125 °C. Note 4: The LT1787C is guaranteed to meet specified performance from 0 °C to 70°C. The LT1787C is designed, characterized and expected to meet specified performance from –40 °C to 85°C but is not tested or QA sampled at these temperatures. The LT1787I is guaranteed to meet specified performance from – 40 °C to 85°C. The LT1787H is guaranteed to meet specified performance from –40 °C to 125°C. Note 5: Testing done at VBIAS = 1.25V, VEE = 0V unless otherwise specified. Note 6: This parameter is not 100% tested.
