CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTE:
1. θ_JA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
Electrical Specifications Test Conditions: V_CC = 3V to 5.5V, C₁ - C₄ = 0.1µF; Unless Otherwise Specified.
Typicals are at T_A = 25°C
