FIELD: automation and computer engineering. ^ SUBSTANCE: proposed "NEGATIVE" logic device (Fig. 2) has binary logic gates 9, 10 or inverters (NOT gates) series-connected between buses of positive and negative voltage supplies 2 and 3, respectively, their inputs being connected to input bus 4 and outputs, to first bus 5 and second bus 6, respectively. Point of connection of power leads of logic gates 9, 10 is connected to common bus so that three potential values of ternary input signal can be judged from voltages across two output buses 5, 6. ^ EFFECT: simplified design of three-value logic inverters. ^ 3 cl, 5 dwg, 7 tbl |
