Abstract: PURPOSE: To provide a programmable logic device having a delay line which has a programmably selectable tap which sends an input to a programmable logic circuit. CONSTITUTION: The delay line tap gives an input to a programmable logic circuit 20 through a logic circuit drive means 18, and the means executes a preparatory processing of a quantity on the tap signal, before it is given to the programmable logic circuit. The output of the programmable logic circuit, which may be a programmable AND array 20 followed by a fixed OR array 22, is given to the edge trigger input of a dual set/reset flip flop. Other outputs of the programmable logic circuit can be selected as the input to the delay line.
