The propagation delay time is defined by test condition as follows: (calculating condition: see Figure 3)
Propagation delay time (reference) = - ( COS + CL ) ・ (RDRIVE+ RON) ・ ln ( ( ( VOH – VOL ) – VM) / ( VOH – VOL ) )
RDRIVE = Output impedance of front circuit
VM= Arbitrary output threshold voltage
Example of calculation:
Propagation delay time (reference) = - ( 15 + 15 ) ・ ( 0 + 21) ・ ln ( ( ( 3.6 - 0 ) – 3.6 ・ 50% ) / ( 3.6 – 0 ) )
= approximately 0.4 ns
Calculating condition:
VCC = 3.6V , CL = 15pF , RDRIVE = 0Ω(ideal signal source) , VM = 50%
Input signal to switch = Digital signal ( “H” revel voltage=3.6V , ”L” revel voltage = 0V )

Note 1: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption without load. Average operating current is given as:
ICC (opr.) = CPD・VCC・fIN + ICC
