NOTICE: This document contains information on

products in the sampling and initial production

phases of development. The specifications are

subject to change without notice.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

VCC (Digital Supply Voltage) .......................... 4.40 V to 5.25 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:

1. Maximum power dissipation is based on package

heat-transfer limitations, not device power

consumption.
