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.
Electrical Characteristics
VCC = 5V for ILC8__L/M/J, VCC = 3.3V for ILC8__S/T, VCC = 3V for ILC8__R, TA = Operating Temperature Range, unless otherwise noted.
