TRI-STABLE STATE CIRCUITRY FOR DIGITAL COMPUTERS

摘要

A tri-stable circuit preferably instrumented in solid state components. The circuit resembles a modified ECCLES-JORDAN "flip-flop" with an extra stage providing a third stable state. The circuit responds to the combination of three input logic values, each in straightforward binary form. Three unique logical output combinations also in binary form are available in response to a like number of possible input combinations.
