A programmable logic circuit of the type known as a PAL (programmable array logic) incorporates a J-K register for each of the circuit outputs. The PAL includes a programmable array for generating products of selected input terms. The product terms available at the array outputs can be programmably allocated to either or both of the J and K inputs. The provision of isolating circuitry allows for simultaneous sharing of each product term by both the J and K inputs.

A test for the input and output circuitry of a logic array including means to disable the AND matrix and means selectively connecting the true and complement output of the input buffers directly to the output circuitry. Means are provided for activating and testing the exclusive OR in the output circuitry and selectively disable one of a combined input/output buffer pair.

A high reliability, low power fuse programmable DC level generator is implemented by providing at least one fuse in each branch of a resistive bridge such that programming of the level generator results in providing a blown fuse in the current path and as a consequence results in low current and low power under all operating conditions.

A programmable logic circuit comprises a Programmable Array Logic (PAL) circuit in which individual product terms may be shared simultaneously by one or more of the circuit outputs. The product terms are selectively connected to the circuit outputs by programmable elements (such as a fusible link) to increase design flexibility. Isolating devices are provided in series with the programmable elements to allow for the simultaneous product term sharing.
