SPECIFICATIONS

ELECTRICAL CHARACTERISTICS—5 V OPERATION

All voltages are relative to their respective ground. 4.5 V ≤ VDD1 ≤ 5.5 V, 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 TA = 25°C, VDD1 = 5 V, VDD2 = 12 V.

Switching specifications are tested with CMOS signal levels.
