Ordering Information
Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. Values are at T
C
 = 25°C unless otherwise noted.
Thermal Characteristics
(1)
Values are at T
= 25°C unless otherwise noted.
Note:
1. PCB size: FR-4 trace width is 50 mil / 25 mil /15 mil, thickness: 2 OZ, minimum land pattern size.
