NOTES:
1. Industrial temperature range product for the 15ns speed grade is available as a standard device. All other speed grades are available by special order.
2. Pulse widths less than minimum values are not allowed.
3. Values guaranteed by design, not currently tested.
4. tSKEW2 applies to synchronous PAE and synchronous PAF only.
