§
Differential voltages are at the B input terminal with respect to the A input terminal.
¶
The algebraic convention, in which the less positive (more negative) limit is designated as minimum, is used in this data sheet for threshold
voltages only.
#
Only one output should be shorted to ground at a time, and duration of the short circuit should not exceed one second.
