Electrical Characteristics (cont’d)
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 VCC = 12 V;
+3.3 V = 3.3 V; +5 V = 5V; +12 V = 12 V; –12 V = –12 V; – 5 V = – 5 V.
