Absolute maximum ratings are those values beyond which the device could be permanently damaged. Note: 1. Absolute maximum ratings are stress ratings only and functional device operation is not implied. Note: 2. All voltages are with respect to the network ground terminal.

For voltage logic levels, the more positive (less negative) limit is designated as maximum, (e.g. if -10V is a maximum, the typical value is a more negative voltage). 2: Output short circuit conditions must maintain the total power dissipation below absolute maximum ratings and the sign is used to indicate direction. 3: Test conditions are those specified by TIA/EIA232-F and as listed above.
