Notes on TTL Output Timing:
1. Output propagation delay time of TTL outputs is the time in nanoseconds from
the 50% point of the reference signal to the 30% or 70% point of the output.
2. Maximum output propagation delays and duty cycles of TTL outputs are
measured with a 15 pF load and 500 ohms to ground on the outputs.
