DC Voltage Applied to Outputs In High-Z State

NOTES:

1.

Stresses greater than those listed under ‘Absolute Maximum Ratings’ may cause permanent damage to the device.

This is a stress rating for transient conditions only. Functional operation of the device at these or any other conditions

outside of those indicated in the ‘Operating Range’ of this specification is not implied. Exposure to absolute maximum

rating conditions for extended periods may affect reliability.

2.

Negative undershoots of 1.5 V in amplitude are permitted for up to 10 ns once per cycle.

3.

Outputs should not be shorted for more than 30 seconds. No more than one output should be shorted at any time.
