AC Characteristics
Capacitive Characteristics
The propagation delay time is defined by test condition as follows: (calculating condition: see Figure 3)
Example of calculation:
Output enable time
Output disable time
Input capacitance
Common Terminal Capacitance
Switch Terminal Capacitance
Feed Through Capacitance
Power dissipation capacitance
Note 1: C
Propagation delay time (reference) = - ( C
Propagation delay time (reference) = - ( 15 + 15 ) ･ ( 0 + 21) ･ ln ( ( ( 3.6 - 0 ) – 3.6 ･ 50% ) / ( 3.6 – 0 ) )
Calculating condition:
