2. CHARACTERISTICS AND SPECIFICATIONS
• Min / Max characteristics and specifications are guaranteed over the Specified Operating Conditions.
• Typical performance characteristics and specifications are derived from measurements taken at nomi-
nal supply voltages and T
A
= 25°C.
• GND, GND1, GND2 = 0 V, all voltages with respect to 0 V.
SPECIFIED OPERATING CONDITIONS
ABSOLUTE MAXIMUM RATINGS
1. Transient currents up to 100 mA will not cause SCR latch-up.
