The speed of operation of a programmable logic device which contains internally synchronous circuit structure is increased by an improved architecture which does not require a power-up transition cycle. Synchronous operation is carried out only for one transition. In each column of the matrix of programmable cells, the rows of which are coupled to receive the logic signals upon which the device is to operate, the programmable cells of that column are coupled via a respective inverter feedback pair to a column output link of the matrix. The connection between the programmable cells of the matrix and the inverter feedback pairs are coupled to pull-down switch devices control inputs of which are coupled to the output of an OR tie, inputs or which depend upon a prescribed transition on row input links. This transition is detected by respective transition detectors which trigger only on a particular transition edge. When the row inputs to the matrix change state, the column outputs follow the transitions asynchronously, with the only delay being that imparted by the inherent delay through the inverter feedback pairs.

A pulse detecting system 1 has a high speed A/D converter 10 and a slew controlled pulse detector 110. The A/D converter 10 has large hysteresis for holding the converted digital value of an input signal V. sub. PULSE until the A/D converter 10 is reset. The slew controlled pulse detector 110 limits the slew rate of large amplitude pulse to correct arrival errors and provide an output signal V. sub. AT that more accurately represents the arrival time of the input pulse signal, V. sub. PULSE.

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.
