(1) 3.3 V: min. is @ 3.6 V; max. is @ 3 V
(2) 5 V: min. is @ 5.5 V; max. is @ 4.5 V
(3) CPD is used to determine the dynamic power consumption, per package.
  1. For AC series: PD = VCC 2 fi (CPD + CL)
  2. For ACT series: PD = VCC 2 fi (CPD + CL) + VCC ΔlCC where fi = input frequency
    1. CL = output load capacitance
    2. VCC = supply voltage.
