7.5 Electrical Characteristics  
Limits apply to the recommended operating junction temperature range of –40°C to 150°C, unless otherwise noted. Minimum  
and maximum limits are ensured 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: Vin = 13.5 V.
