NOTES:
1. All voltages referenced to device GND.
2. 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:
1TTL gate equivalent, CL = 50pF (min) - for CL greater than 50pF, access time is derated by 0.15ns per pF.
3. TAVQV = TELQV + TAVEL.
