Mil-Std-883, method 5005, subgroups 9, 10, 11
Notes:
1. t = CK4 period, t₁₂ = CK12 period
2. Times quoted as typical means a fixed number of CK4 clock cycles but excludes slight variations due to
propagation delays.
Conditions: V_dd = 4.5 to 5.5V, T_amb = -55°C to +125°C, V_IL = 0V, V_IH = 4V, V_OUT Threshold = 1.5V except t₂ where measured
by a 1V change in output voltage. Load = 50pf except t₂ where additional 1K load to 0V or V_DD.
