Brief description
Timer with OFF delay
Mode of operation
The falling edge of a pulse at input I resets output Q to 0 after OFF delay time T.
Output Q becomes 1 when I is 1.
Output Q becomes 0 when input pulse I is 0 and OFF delay time T has expired.
If input I is reset to 1 before time T has expired, output Q remains 1.
