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.

NOTES:

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.

5. All voltages are with respect to GND.

Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to Figure 1 on page 2 and Figure 2 on

page 3. VDD = 5V, CLK = 50kHz, TA = -40 to +105°C (Note 6), Typical values are at TA = +25°C
