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 reliabil-

ity. Operating ranges define those limits between which the functionality of the device is guaranteed.

VCC = 5V for ILC81_L/M/J, VCC = 3.3V for ILC81_S/T, VCC = 3V for ILC81_R, TA = Operating Temperature Range, unless

otherwise noted.
