Brief description
Timer for generating a pulse with a minimum duration and an additional reset input
Mode of operation
The rising edge of a pulse at input I sets output Q to 1.
Output Q does not return to 1 until input pulse I is 0 and pulse duration T has expired.
Output Q can be set to zero at any time via reset input R with R = 1.
Time flow chart
Output pulse Q as a function of pulse duration T and input pulse I (when R = 0).
