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, see the Electrical Characteristics tables.
Note 2: For testing purposes, ESD was applied using “Human Body Model”; 1.5 k
Ω in series with 100 pF.
Note 3: Machine Model, 0
Ω in series with 200 pF.
Note 4: 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.
Note 5: 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 onto a PC board..
Note 6: Typical values represent the most likely parametric norm.
Note 7: All limits are guaranteed by testing or statistical analysis.
Note 8: Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of
the device such that TJ =TA. There is no guarantee of parametric performance as indicated in the electrical tables under conditions of internal self-heating where
TJ > TA. See Applications section for information on temperature de-rating of this device.
Note 9: VGPD = ground potential difference voltage between driver and receiver
Note 10: This figure is taken from a thermal modeling result. The test board is a 4 layer FR-4 board measuring 101 mm x 101 mm x 1.6 mm witha3x3 array of
thermal vias. The ground plane on the board is 50 mm x 50 mm. Ambient temperature in simulation is 22˚C, still air. Power dissipation is 1W.
Note 11: This is the average between the positive and negative overshoot.
Note 12: Total input current is 4 mA (all 4 channels equal) and output currents are summed together (see typical performance characteristics).
