GND = 0 V; CL = 50 pF; for load circuit see Figure 6.
propagation delay nA, nB to nY; see Figure 5
VCC = 4.5 V
VCC = 5.0 V; CL = 15 pF
VCC = 4.5 V; see Figure 5
power dissipation per package;
VI = GND to VCC 1.5 V
 tpd is the same as tPHL and tPLH.
 tt is the same as tTHL and tTLH.
 CPD is used to determine the dynamic power dissipation (PD in W):
PD = CPD VCC2 fi N + (CL VCC2 fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
(CL VCC2 fo) = sum of outputs.
40 C to +125 C Unit

Measurement points are given in Table 9.
VOL and VOH are typical voltage output levels that occur with the output load.
