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.

Description

Ground Pin.

RESET goes low if VCC falls below the reset

threshold and remains asserted for one reset timeout

period (140ms min.) after VCC exceeds the reset

threshold.

RESET goes high if VCC falls below the reset

threshold and remains asserted for one reset timeout

period (140ms min.) after VCC exceeds the reset

threshold.

Power supply input, 3 V, 3.3 V or 5 V.
