* Refer to the Test Conditions on Page 24 for details.
Note:
1. Typical figures are at 25^oC and are for design aid only; not production tested.
2. The maximum and minimum timing is measured under recommended temperature conditions and power supplies.
3. TTL voltage levels are used for timing parameter measurement.
