Note 1:
All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 2:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is func-
tional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which guar-
antee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit is
given, however, the typical value is a good indication of device performance.
Note 3:
See AN-450 for other methods of soldering surface mount devices, and also AN-1112 for micro SMD considerations.
Note 4:
If the RESET pin is to be used at temperatures of −20˚C and below V
S
is required to be 2.0V or greater.
Note 5:
