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
in series with 100 pF.
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 150C. Output current in excess of
±
30 mA over long term may adversely affect reliability.
Note 4:
The maximum power dissipation is a function of T

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

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 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.
Note 16:
The V
(threshold low and threshold high) limits are guaranteed at room temperature and at temperature extremes. Room temperature limits are produc-
tion tested. Limits at temperature extremes are guaranteed via correlation using temperature regression analysis methods. Refer to Section 6.2 for an overview of
the threshold voltages.
