Absolute Maximum Ratings*
*Notice: Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent
damage to the device. This is a stress rating
only and functional operation of the device at
these or any other conditions beyond those
indicated in the operational sections of this
specification is not implied. Exposure to
Operating Temperature . . . . . . . . . . .-55C to +125C
Storage Temperature . . . . . . . . . . . . .-65C to +150C
Voltage on any pin
with respect to ground . . . . . . . . . . . . . -1.0V to +7.0V
Maximum Operating Voltage . . . . . . . . . . . . . . . 6.25V
DC Output Current . . . . . . . . . . . . . . . . . . . . . . .5.0mA
absolute maximum rating conditions for
extended periods may affect device reliability.
