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: Vdd = 4.5 to 5.5V, Tamb = -55°C to +125°C, VIL = 0V, VIH = 4V, VOUT 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 VDD.
