the commercial junction temperature range (0° to 85° C), the industrial
junction temperature range (–40° to 100° C), the automotive junction
temperature range (–40° to 125° C), and the extended temperature range
(–40° to 125° C). Follow the PLL specifications for –8 speed grade devices
when operating in the industrial, automotive, or extended temperature
range.
