NOTES:

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause

permanent damage to the device. This is a stress rating only and functional operation

of the device at these or any other conditions above those indicated in the operational

sections of this specification is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect reliability.

2. The input and output negative-voltage ratings may be exceeded if the input and output

clamp-current ratings are observed.

3. The maximum package power dissipation is calculated using a junction temperature

of 150°C and a board trace length of 750 mils.

NOTES:

1. Weak pull down.

2. Weak pull down on all outputs.
