Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is in-
tended 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
Note 3: Applies to both single-supply and split-supply operation. Continous short circuit operation at elevated ambient temperature can result in exceeding the maxi-
mum allowed junction temperature of 150˚C. Output current in excess of

tive slew rates.
Note 11: Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings.
Note 12: Guaranteed limits are dictated by tester limitations and not device performance. Actual performance is reflected in the typical value.
Note 13: CMRR
For CMRR
Note 14: V
Note 15: The propogation delays are measured using an input waveform of f = 5 Hz, and magnitude of 2.4V. Refer to Section 6.3 and Figures 14, 15 for a detailed
explanation.
