Abstract :
An asynchronous version of a binary pixel readout circuit has been implemented in an array with 16 columns at 500 mu m pitch and 63 rows at 75 mu m pitch. This readout chip has been bonded with solder bumps to a silicon detector with matching pixel elements. Event information in a pixel can be strobed into a local memory by a trigger signal and subsequently read out. Without a strobe the information in this memory is continuously cleared. The complete hybrid detector has been successfully tested with ionizing particles from a radioactive source. Three such devices have been used in the CERN heavy ion experiment WA94 in the Omega spectrometer where they recorded particle tracks from high multiplicity /sup 32/S interactions.<>
