Notes
1. H = HIGH state (the more positive voltage)
2. L = LOW state (the less positive voltage)
3. X = state is immaterial
4.
= positive-going transition
5.
= negative-going transition
6.
= positive or negative output pulse; width is determined by Ct and Rt
AC CHARACTERISTICS
VSS = 0 V; Tamb = 25 °C; CL = 50 pF; input transition times ≤ 20 ns
