Figure 34 Test Condition of Response Time
Figure 35 Test Circuit of Response Time
Caution 1. The above connection diagram and constant will not guarantee successful operation.
Perform thorough evaluation using the actual application to set the constant.
2. When the CD pin is open, a double pulse may appear at release.
To avoid the double pulse, attach a 100 pF or more capacitor to the CD pin.
Response time when detecting (tPHL) is not affected by CD pin capacitance. Besides, response
time when releasing (tPLH) can set the delay time by attaching the CD pin.
Refer to "11. Delay time
(tD) vs. CD pin capacitance (CD) (Without output pin capacitance)" for
details.
