pF

(1)

CPD is used to determine the dynamic power consumption, per channel

(2)

PD= VCC 2xFIx(CPD+ CL) where FI= input frequency, CL= output load capacitance, VCC= supply voltage

5.6 Switching Characteristics

CL = 50pF; over operating free-air temperature range; typical values measured at TA = 25°C (unless otherwise noted). See
