Notes:
1. To check the reset circuit ,the reset output is low to discharge the delay capacitor(=Cd). if it’s less than V_O1-0.25V.
And the reset output is high when the delay capacitor voltage linearly increased by the interal current source(10µA)
if it’s more than V_O1- 0.2V. The equations of delay time is same as below. Trd = (Cd X 2.5) / 10µA
2. These parameters, although guaranteed, are not 100% tested in production.
