ABSTRACT:
An integrated circuit device which implements a plurality of programmable digital logic functions derived from a number of digital logic inputs and further includes an on-chip digital-to-analog converter providing an analog output current signal responsive to the programmable logic functions derived from the digital inputs is provided. The means for implementing the programmable logic functions may include a programmable logic circuit having a programmable AND array comprising a plurality of AND gates, each with a plurality of inputs and at least one output. The AND gate inputs are selectively programmable with the input terms to generate an output signal to the AND gate outputs. The device further includes an OR gate array having a plurality of OR gates, each of the OR gates including a plurality of inputs and an output, thereby providing a plurality of OR gate array outputs generating a plurality of digital logic signals. The digital-to-analog converter includes a plurality of inputs coupled to a subset of the plurality of OR gate array outputs for converting the digital signals present on the OR gate array outputs into a variable amplitude output signal. In one embodiment, an 8-to-8 encoder providing the outputs of the subset of OR gate array outputs to the inputs of the digital-to-analog converter is also included.
