Abstract

PURPOSE:To make small the chip size by reducing the number of elements and quickening the operation speed, through the input of timing signal is series with the OR term, in the programmable logic array constituted with AND term and OR term. CONSTITUTION:The input signals A, B, C and their inversion signals are inputted to the AND term 101 consisting of the NOR circuits 4, 5, 6, 7, and the different outputs 20S and 21S are introduced by multiplex in time sharing manner from the OR term 104 consisting of the AND and OR circuits 20 and 21. In consitituting this circuit on the semiconductor substrate, the timing signal T2 is inserted in series between the part 222 treating OR for the outputs 4S and 5S of the AND term 101 and the power supply 211, and the output line 221 is in common use with the output line of other AND OR circuit 212. Accordingly, the number of elements is reduced than the case with normal constitution and the length of wiring can be made shorter
