CEN is also used for providing immunity to pin EN against fast transient noises. Therefore

the value of CEN should be chosen as big as possible according to the maximum tolerable

delay time and the REN value should be chosen according to the desired disable time.

The resistor REN should be chosen in the range from 2.2 K to 180 K. Recommended

values for REN and CEN are respectively 100 K and 5.6 nF that allow obtaining 200 s

disable time.
