Abstract
Relay multiplexer circuitry for making a limited number of test channels connectable to a large number of test pins through relays connected to selected test channel nodes and test pin nodes, each test pin node being connectable to a unique combination of test channel nodes within a group of pin nodes, channel nodes and relays, the number of pin nodes connectable to each channel node being substantially uniform within a group to efficiently use channels to reduce the possibility of conflict.
