Parameters are valid over the specified temperature and operating supply ranges. Typical values are 25°C, V
processing parameters.
All voltages are referenced to ground (GND). For testing, input signal levels are 0.4V and 2.4V with a transition time of 20ns
maximum. All time measurements are referenced at input voltages of 0.8V and 2.0V as appropriate. See Figure 50.
For prime grade N, P, J, L, M, ML, V
Measured operating with a 3.6864MHz crystal and with all outputs open.
