*Stresses above those listed in "Absolute Maximum Ratings" may cause
permanent damage to the device. These are stress ratings only and
functional operation of the device at these or other conditions above those
indicated in the operation section of the specification is not implied.
Exposure to the Absolute Maximum Ratings conditions for extended
periods of time may affect device reliability.
ELECTRICAL CHARACTERISTICS: VIN = +5V, TA = +25°C, test circuit Figure 1, unless otherwise indicated.
