RESET/OE Hold Time (guarantees counters are reset)
CE High time (guarantees counters are reset)
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 V
IL
= 0.0V and V
IH
= 3.0V.
