Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

4. Typical values are measured at TA = 25

°C and VCC = 3.3 V, unless stated otherwise.

5. tpd is the same as tPLH and tPHL.

6. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device.

The specification applies to any outputs switching in the same direction, either HIGH−to−LOW (tOSHL) or LOW−to−HIGH (tOSLH); parameter

guaranteed by design.

8. CPD is used to determine the dynamic power dissipation (PD in mW).

PD = CPD x VCC2 x fi x N + S (CL x VCC2 x 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 outputs switching

S(CL x VCC2 x fo) = sum of the outputs.
