ELECTRICAL CHARACTERISTICS
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: V
Note 3: Pins 1, 3 and 8 (OUT) should be tied together with a low
impedance to ensure that the difference between the three pins does not
exceed 50mV. Pins 2, 4 and 5 (BAT) should be tied together with a low
impedance to ensure that the difference between the three pins does not
exceed 50mV.
Note 4: All voltage values are with respect to GND.
Note 5: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions. Junction

Continuous operation above the specifi ed maximum operating junction
temperature may impair device reliability.
Note 6: The LTC4066/LTC4066-1 are guaranteed to meet performance
specifi cations from 0°C to 70°C. Specifi cations over the –40°C to 85°C
operating temperature range are assured by design, characterization and
correlation with statistical process controls.
