Absolute Maximum Ratings*
Operating Temperature .................................. -55掳C to +125掳C
*NOTICE:
Stresses beyond those listed under 鈥淎bsolute
Maximum Ratings鈥?may cause permanent dam-
age 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 absolute maximum rating
conditions for extended periods may affect device
reliability.
Storage Temperature ..................................... -65掳C to +150掳C
Voltage on Any Pin
with Respect to Ground .....................................-1.0V to +7.0V
Maximum Operating Voltage............................................. 6.6V
DC Output Current...................................................... 15.0 mA
