Abstract :
A set of tri-stable RSFQ cells has been designed, simulated, fabricated in Hypres, Inc. using 1 kA/cm/sup 2/ low-T/sub c/ Niobium technology and successfully tested. The elements (including a generic X cell, XOR and inverted XOR cells) are fully compatible with binary RSFQ circuits and do not require any input/output conversion. Their use provides an effective way to simplify some complex functional RSFQ blocks. We also describe a novel automated setup for testing of digital superconductive devices which has been used for experimental study of the cells.<>
