NOTES:

1. Input pulse levels: 0.8V to VCC - 2.0V; Input rise and fall times: 5ns (max); Input and output timing reference level: 1.5V; Output load:

1 TTL gate equivalent, CL = 50pF (min) - for CL greater than 50pF, access time is derated by 0.15ns per pF.

2. Tested at initial design and after major design changes.

3. VCC = 4.5V and 5.5V.

4. TAVQV = TELQV + TAVEL.
