3 www.fairchildsemi.com 74FR16540 Absolute Maximum Ratings(Note 1) Recommended Operating Conditions Note 1: Absolute maximum ratings are values beyond which the device may be damaged or have its useful life impaired. Functional operation under these conditions is not implied. Note 2: Either voltage limit or current limit is sufficient to protect inputs.

www.fairchildsemi.com 4 74FR16540 Extended AC Characteristics Note 3: Skew is defined as the absolute value of the difference between the actual propagation delays for any two outputs of the same device. The specifi- cation applies to any outputs switching HIGH-to-LOW (tOSHL ), LOW-to-HIGH, (tOSLH ), or HIGH-to-LOW and/or LOW-to-HIGH, (tOST ). Specifications guaran- teed with all outputs switching in phase. This specification is guaranteed but not tested. Note 4: This specification is guaranteed but not tested. The limits apply to propagation delays for all paths described switching in phase, i.e., all LOW-to-HIGH, HIGH-to-LOW, 3-STATE-to-HIGH, etc. Note 5: These specifications guaranteed but not tested. The limits represent propagation delays with 250 pF load capacitors in place of the 50 pF load capacitors in the standard AC load. This specification pertains to single output switching only.
