DC CHARACTERISTICS

Absolute Maximum Ratings

Maximum rating are the worst case limits that the device can withstand without

sustaining permanent damage. They are not indicative of normal mode operation

conditions.

NOTE: the PM3351 has been characterized over the industrial temperature range (Ta =

-40°C to +85°C). All DC and AC parametrics met the limits presented in the following

tables. In addition the package thermal characteristics of the 208 pin PQFP package

and power consumption of the device are such that the device can be operated without

any forced air (i.e. still air) over the full commercial temperature range; however, if

operating over the industrial temperature range (which has a maximum ambient

temperature of +85 °C) a minimum airflow of 100 linear feet per minute is required.
