6.6 Timing Requirements
The electrical ratings specified in this section apply to all specifications in this document unless otherwise noted. These specifications are interpreted as conditions that will not degrade the parametric or functional specifications of the device for the life of the product containing it. Typical values correspond to TJ = 25°C, VIN = 12 V. Minimum and maximum limits are based on TJ = –40°C to +150°C, VIN = 4.5 V to 28 V(unless otherwise noted).
