(3) Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in
exceeding the maximum allowed junction temperature of 150°C. Output currents in excess of ±30mA over long term may adversely
affect reliability.
(4) The LMV7219 comparator has internal hysteresis. The trip points are the input voltage needed to change the output state in each
direction. The offset voltage is defined as the average of V
trip
+
and V
trip
−
, while the hysteresis voltage is the difference of these two.
(5) Propagation delay measurements made with 100 mV steps. Overdrive is measured relative to V
Trip
.
(6) Propagation Delay Skew is defined as absolute value of the difference between t
PDLH
and t
PDHL
.
