ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect
reliability.
Power Supply, V_DD.................................................7.0V
Input Voltages, Logic.....................-0.3V to (V_DD+0.3V)
Lamp Outputs...................................................220V_P-P
Operating Temperature.........................-40˚C to +85˚C
Storage Temperature..........................-65˚C to +150˚C
Power Dissipation Per Package
10-pin µSOIC
(derate 8.84mW/˚C above +70˚C)....................720mW
STORAGE CONSIDERATIONS
Storage in a low humidity environment is pre-
ferred. Large high density plastic packages are
moisture sensitive and should be stored in Dry
Vapor Barrier Bags. Prior to usage, the parts
should remain bagged and stored below 40°C and
60%RH. If the parts are removed from the bag,
they should be used within 48 hours or stored in an
environment at or below 20%RH. If the above
conditions cannot be followed, the parts should be
baked for four hours at 125°C in order remove
moisture prior to soldering. Sipex ships product in
Dry Vapor Barrier Bags with a humidity indicator
card and desiccant pack. The humidity indicator
should be below 30%RH.
