10. Dynamic characteristics
[1]
Typical values are measured at Tamb =25 C and VCC = 1.2 V, 1.8 V, 2.5 V, 2.7 V, and 3.3 V respectively.
[2]
tpd is the same as tPLH and tPHL.
ten is the same as tPZL and tPZH.
tdis is the same as tPLZ and tPHZ.
[3]
Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed by design.
[4]
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 Volts
N = number of inputs switching

Dynamic characteristics
Voltages are referenced to GND (ground = 0 V). For test circuit see Figure 7.
