Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

Notes: 1. CPD is used to determine the dynamic power dissipation (PD in μW).
PD  C P D  V C2C  f i  N   ( C L  V C2C  f O ) , where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in Volts;
N = total load switching outputs;
 ( C L  V C2C  f O ) = sum of outputs.
2. The condition is VI = GND to VCC.
