<p>1,135,268. Bi-stable logic circuits. INTERNATIONAL BUSINESS MACHINES CORP. 7 March, 1966 [5 April, 1965], No. 9819/66. Heading H3T. A bi-stable circuit comprises a pair of reciprocably coupled SET and RESET circuits, switched by the simultaneous application of clock and data setting signals which gate a data input signal applied selectively either to air input of the SET circuit or to an input of the RESET circuit. Each circuit may comprise a transistor inverting OR 4, 8, controlled by AND circuits 1 ... 7. The selective application of data input signals BIT A (or BIT B) is arranged by feeding such signals directly to the SET circuit and via an inverter 9 (or 10) to the RESET circuit.</p> |
