*Notice: Stresses beyond those listed under “Absolute Maximum Rat-

ings” may cause permanent damage to the device. These are stress

ratings only, and functional operation of the device at these or any other

conditions beyond those indicated in the operational sections of the

specifications is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect device reliability.

ELECTRICAL CHARACTERISTICS

VDD = 5V for L/M versions, VDD = 3.3V for T/S versions, VDD = 3V for R version, VDD = 2.0V for F version.

Unless otherwise noted, TA = –40°C to +85°C. Typical values are at TA = +25°C. (Note 1)
