    摘要: A method and electronic network for limiting the electrical noise arising during transmission of digital data signals from a first integrated circuit having multiple output devices at which the data signals are formed to the input of a second integrated circuit. The method and network feature steps and means for sensing the conduction state of the first integrated circuit devices and for generating a control signal to invert the data signals before transmission when the number of output devices conducting is equal to or greater than a predetermined number. The method and network also feature steps and means for transmitting the data signals and control signal so that the data signals may be reconstituted to establish the data signals as they appear at the first integrated circuit output, before the data signals are presented to the second integrated circuit input.

    摘要: A latch that can serve as a bit storage cell in a random-access store. The latch includes an AND gate (diodes D1 and D2) the input IN of which receives the bit to be stored and the other input of which is connected to a write control line WRL. When no write operation is being performed, transistor T1 is turned off and the state of transistor T2 is dependent on output potential OUT. To perform a write operation, line WRL is activated (goes high) and the state of transistor T3 will depend on the value of the bit applied to input IN. Read operations are performed by means of another AND gate (diodes D4 and D5) and an emitter follower (transistor T4) connected via a bit line BL to an output circuit 2. By adding input transistors and emitter followers to the latch, a multi-port storage can be realized, several rows of which can be simultaneously written into and/or read out.
