Dual D-type flip-flop with set and reset; positive-edge trigger
[1]
Typical values are measured at Tamb = 25 °C.
[2]
tpd is the same as tPHL and tPLH.
[3]
Typical value measured at VCC = 3.3 V.
[4]
Typical values are measured at VCC = 5.0 V.

CPD is used to determine the dynamic power dissipation PD = CPD VCC2 fi + (CL VCC2 fo) (PD in W), where:
fi = input frequency in MHz;
fo = output frequency in MHz;
