ELECTRICAL CHARACTERISTICS
Notes:
1. To check the reset circuit ,the reset output is low to discharge the delay capacitor(=Cd). if it’s less than
And the reset output is high when the delay capacitor voltage linearly increased by the interal current source(10µA)
if it’s more than
2. These parameters, although guaranteed, are not 100% tested in production.
