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.
