PARAMETER
SYMBOL
Note 1:
Inferred from the CMRR test. Note also that either or both inputs can be driven to the absolute maximum limit (0.3V
beyond either supply rail) without damage or false output inversion.
The input-referred trip points are the extremities of the differential input voltage required to make the comparator output
change state. The difference between the upper and lower trip points is equal to the width of the input-referred hysteresis
zone. See Figure 1.
V
OS
is defined as the center of the input-referred hysteresis zone. See Figure 1.
The polarity of I

reverses direction as V
CM
approaches either supply rail. See Typical Operating Characteristics for more
detail.
Specified over the full common-mode range (V
