Maximum Ratings
(Above which useful life may be impaired. For user guidelines, not tested.)
Storage Temperature ......................................... –65°C to +150°C
Note: Stresses greater than those listed under MAXIMUM RAT-
INGS 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 above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
Supply Voltage to Ground Potential
.............–0.5V to +4.0V
DC Input Voltage .................................................–0.5V to +5.5V
DC Output Current............................................................ 120mA
Power Dissipation................................................................ 0.5W
