Abstract

1,251,634. Transistor bi-stable circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 7 Jan., 1970 [14 Jan., 1969], No. 827/70. Heading H3T. [Also in Divisions G4-G6] Digital data is shifted from one register to another through serially connectible diodes. A register, for example register A, comprises integrated circuit bi-stable cells AFF1, AFF2 each bi-stable state of which can exist in three states: normal, receive or transmit (Figs. 2A to 2C, not shown). The normal, receive and transmit states are effected by biasing the emitter to 0, + 1 V., or - 1 V. respectively and the bistables are two conventional cross-coupled transistors. To transmit a binary digit from a cell in one register to a cell in one or more other registers, a computer causes the appropriate switches " A Reg SW, B Reg SW &c." to simultaneously put the appropriate cells into the transmit or receive states, the resulting voltage overcoming the bias of the diodes to transfer the digit. Data can be transmitted in parallel to a register which can then return it to the original register skewed as many digits to the right or left as desired, thus replacing a shift register. It can also be used for complementing a word.
