ELECTRICAL CHARACTERISTICS—3.3 V OPERATION

All voltages are relative to their respective ground. 3.0 V ≤ VDD1 ≤ 3.6 V, and 4.5 V ≤ VDD2 ≤ 18 V, unless stated otherwise. All minimum/

maximum specifications apply over TJ = −40°C to +125°C. All typical specifications are at TJ = 25°C, VDD1 = 3.3 V, and VDD2 = 12 V.

Switching specifications are tested with CMOS signal levels.
