Room = 25_C, Cold and Hot = as determined by the operating temperature suffix.
The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
Guaranteed by design, not subject to production test.
Minimum pulse width to reset a fault condition.
