ABSOLUTE MAXIMUM RATINGS
Input Voltage, VDD
Output Sustaining Voltage, VLEDn
Voltage at all other pins
Maximum Junction Temperature, TJ
Storage Temperature Range
Lead Temperature (soldering, 10 seconds)
(Note)
Note:
Exceeding these ratings could cause damage to the device. All voltages are with respect to Ground.
Currents are positive into, negative out of the specified terminal.

Note :
Junction Temperature Calculation: TJ = TA + (PD x θJA).
PD: Power Dissipation, TA: Ambient temperature, θJA: Thermal Resistance-Junction to Ambient
The θJA numbers are guidelines for the thermal performance of the device/PC-board system.
All of the above assume no ambient airflow.
