Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other conditions above indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

Electrical Characteristics
Electrical Characteristics are guaranteed over full junction temperature range (0 to 105
°
C). Ambient temperature must be derated
based on power dissipation and package thermal characteristics. Unless otherwise specified, the conditions of test are V
CC
= 12 V;
+3.3 V = 3.3 V; +5 V = 5V; +12 V = 12 V; –12 V = –12 V; –5 V = –5 V; OFF = low.
