† Notice: Stresses above 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 those or any other conditions above those indicated

in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended

periods may affect device reliability.

‡ Notice: The device is not guaranteed to function outside its operating rating.

Note 1: Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5 kΩ in series

with 100 pF.

ELECTRICAL CHARACTERISTICS

Electrical Characteristics: For typical values, VCC = 5V for MIC81_L/M/J, VCC = 3.3V for MIC81_S/T, VCC = 3V for

MIC81_R; TA = +25°C, bold values indicate –40°C to ≤ TA ≤ +85°C; unless noted. (Note 1)
