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:
4. _JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
NOTE: Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
Electrical Specifications V_DD = 5V, T_A = +25°C, ENABLE = HI, WEN = HI, OSCEN = LO, SEL1 = HI, unless otherwise specified.
