Notes
1._{Parameters are valid over the specified temperature and operating supply ranges. Typical values are 25
C, VCC = 5V and typical}
processing parameters.
2._{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.
3._{For prime grade N, P, J, L, M, ML, VCC = 5V + 10%.}
4._{Measured operating with a 3.6864MHz crystal and with all outputs open.}
