Note 1: All device specifications are 100% production tested at T
A
= +25°C. Limits over the extended temperature range are guar-
anteed by design.
Note 2: Inferred from the V
OS
test. Both or either inputs can be driven 0.3V beyond either supply rail without output phase reversal.
Note 3: V
OS
is defined as the center of the hysteresis band at the input.
Note 4: I
B
is defined as the average of the two input bias currents (I
B-
, I
B+
).
