7.5 Electrical Characteristics

Limits apply over the junction temperature (TJ) range of –40°C to 150°C, unless otherwise stated. Minimum and maximum limits are specified through test, design or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only. Unless otherwise stated, the following conditions apply: VVDD = 12 V(1).

(1) MIN and MAX limits are 100% production tested at 25ºC unless otherwise specified. Limits over the operating temperature range verified through correlation using Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality Level (AOQL).
(2) Capacitance chosen for effective test only. Do not use this capacitance in applications.  
(3) Parameter specified by design, statistical analysis and production testing of correlated parameters.
