NOTES:

2. For TTL inputs add 5 mA ICC.

3. These are absolute voltages with respect to device ground pin and include all overshoots due to system and/or tester noise.

Do not attempt to test these values without suitable equipment.

Stresses above 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 of

time may affect device reliability.
