NOTES:
1. Due to symmetrical geometry, these units may be operated with source and drain leads interchanged.
2. This parameter is measured during a 2 ms interval 100 ms after power is applied. (Not a JEDEC condition.)
Linear Integrated Systems (LIS) is a 25-year-old, third-generation precision semiconductor company providing
high-quality discrete components. Expertise brought to LIS is based on processes and products developed
at Amelco, Union Carbide, Intersil and Micro Power Systems by company President John H. Hall. Hall,
a protégé of Silicon Valley legend Dr. Jean Hoerni, was the director of IC Development at Union Carbide,
co-founder and vice president of R&D at Intersil, and founder/president of Micro Power Systems.
