TABLE 1-1:
DC CHARACTERISTICS
NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at those or any other conditions above those
indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.
All parameters apply over the specified
ranges unless otherwise noted.
VCC = range by device (see Table on Page 1)
Industrial (I):
TA = -40°C to +85°C
Automotive (E):
TA = -40°C to +125°C
