Retentive on delay

A specified time starts after an input pulse. The output is set on expiration of this time.

As soon as the status at the input Trg changes from Lo to Hi, the specified time starts. After expiration on the configured time, the output Q is set to Hi. Further switching actions at input Trg have no influence on the running time. The output and the time are only reset to Lo when the status at input R is Hi.
