11. Dynamic characteristics
[1]
tpd is the same as tPLH and tPHL.
ten is the same as tPZL and tPZH.
tdis is the same as tPLZ and tPHZ.
[2]
CPD is used to determine the dynamic power dissipation PD (W).
PD =CPD × VCC2 × fi + ∑ (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
∑ (CL × VCC2 × fo) = sum of outputs
Table 8.
Dynamic characteristics
GND = 0 V; tr = tf ≤ 6.0 ns; CL = 50 pF unless otherwise specied. All typical values are measured at Tamb =25 °C. For test
circuit see Figure 7
