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, VDD.................................................7.0V
Input Voltages, Logic.....................-0.3V to (VDD+0.3V)
Lamp Outputs...................................................220VP-P
Operating Temperature.........................-40˚C to +85˚C
Storage Temperature..........................-65˚C to +150˚C
Power Dissipation Per Package
14-pin SOIC
(derate 8.33mW/˚C above +70˚C)....................700mW
14-pin TSSOP
(derate 9.96mW/˚C above +70˚C)....................800mW
STORAGE CONSIDERATIONS
Storage in a low humidity environment is preferred.
Large high density plastic packages are moisture sen-
sitive 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 prod-
uct in Dry Vapor Barrier Bags with a humidity indicator
card and desiccant pack. The humidity indicator should
be below 30%RH.
