Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

NOTES
1. ALTHOUGH NOT REQUIRED IN ALL APPLICATIONS, THE EXPOSED PADDLE
ON THE UNDERSIDE OF THE PACKAGE SHOULD BE SOLDERED TO THE
GROUND PLANE. SOLDERING THE EXPOSED PADDLE TO THE PCB
INCREASES THE RELIABILITY OF THE SOLDER JOINTS, MAXIMIZING
THE THERMAL CAPABILITY OF THE PACKAGE.

Exposed Pad
(TQFP_EP)
Although not required in all applications, the exposed paddle on the underside of the TQFP_EP
package should be soldered to the ground plane. Soldering the exposed paddle to the PCB
increases the reliability of the solder joints, maximizing the thermal capability of the package.
