With every change at the input Tr a pulse occurs at the output Q. If the change at Tr is from 0 to 1 then a pulse also occurs at Qon. When the state of Tr changes from 1 to 0 then a pulse occurs at the output Qoff.
The duration of the pulses at the outputs is set with the parameter T.
The input R causes a pulse to occur at Qoff whenever a pulse triggers R.
The input O does the same thing in reverse causing a pulse at Q and Qon.
If the input Dis is enabled then the inputs are locked.
