Notes:
1.
AC test load = 50 pF
2.
Guaranteed by design, not tested.
3.
Float delays are measured with 5 pF AC loads. Transition is measured at ±200 mV from steady state active levels.
4.
All AC parameters are measured with VIL = 0.0V and VIH = 3.0V.
5.
If TCEH High < 2μs, TCE = 2 μs.
6.
If THOE High < 2μs, TCE = 2 μs.
