withstand sustained short circuit
without damage.
Storage Temperature –55 to +125°C
Lead Temperature See soldering guidelines
Absolute maximums are stress ratings. Exposure of devices to greater than
any of these conditions may adversely affect long-term reliability. Proper
operation under conditions other than those listed in the Performance/
Functional Specifi cations Table is not implied or recommended.
