Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is

intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical characteristics.

Note 2: Human body model, 1.5 k

Ω in series with 100 pF. Machine model, 200Ω in series with 100 pF.

Note 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.

Note 4: The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is

PD =(TJ(MAX) -TA)/θJA. All numbers apply for packages soldered directly into a PC board.

Note 5: Typical Values represent the most likely parametric norm.

Note 6: All limits are guaranteed by testing or statistical analysis.

Note 7: Propagation delay measurements made with 100 mV steps. Overdrive is measure relative to VTrip.

Note 8: Propagation Delay Skew is defined as absolute value of the difference between tPDLH and tPDHL.

Note 9: Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings.

Note 10: 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 Vtrip+ and Vtrip−, while the hysteresis voltage is the difference of these two.
