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 FM81_L/M/J, VCC = 3.3V for FM81_S/T, VCC = 3V for FM81_R, TA = Operating Temperature Range,

unless otherwise noted.
