NOTICE:This document contains information on

products being sampled or in the initial production

phase of development. Verify with your local Intel

sales office that you have the latest datasheet

before finalizing a design.

OPERATING CONDITIONS

TA (Ambient Temperature Under Bias):

Commercial ................................................. 0°C to +70°C

Express........................................................... -40°C to +85°C

VCC (Digital Supply Voltage) ............................ 4.5 V to 5.5 V

VSS ................................................................................... 0 V

WARNING: Stressing the device beyond the

“Absolute Maximum Ratings” may cause

permanent damage. These are stress ratings only.

Operation beyond the “Operating Conditions” is not

recommended and extended exposure beyond the

“Operating Conditions” may affect device

reliability.

NOTE:Maximum power dissipation is based on

package heat-transfer limitations, not device power

consumption.
