Stresses above those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent device failure. Functionality at or above these limits is not implied. Exposure to absolute

maximum ratings for extended periods may affect device reliability. Operating ranges define those limits between which the functionality of the device is guaranteed.

Electrical Characteristics

VCC = 5V for MIC8--L/M/J, VCC = 3.3V for MIC8--S/T, VCC = 3V for MIC8--R, TA = Operating Temperature Range, unless

otherwise noted.
