Absolute Maximum Ratings
Voltage on VDD Supply Relative to VSS-0.5V to +2.8V
Voltage on VDDQ Supply
Relative to VSS ....................................... -0.5V to +VDD
VIN ..................................................... -0.5V to VDD + 0.5V
Storage Temperature ..............................-55C to +125C
Junction Temperature .......................................... +125C
Short Circuit Output Current .............................. ±70mA
Stresses greater than those listed under Absolute
Maximum Ratings may cause permanent damage to
the device. This is a stress rating only, and functional
operation of the device at these or any other condi-
tions above those indicated in the operational sections
of this specification is not implied. Exposure to abso-
lute maximum rating conditions for extended periods
may affect reliability.
Maximum Junction Temperature depends upon
package type, cycle time, loading, ambient tempera-
ture, and airflow.
