6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted) (1)
MINMAXUNIT
DC voltage applied to data, VPU–0.37V
Low-level output current, IOL40mA
ESD IEC 61000-4-2 air discharge, data to VSS, VSS to data15kV
Operating free-air temperature, TA–2070°C
Communication free-air temperature, TA(Comm)(2)–4085°C
Junction temperature, TJ125°C
Storage temperature, Tstg–55125°C
(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.
(2) Communication is specified by design.
