Abstract: 1289527 Transistor bi-stable circuits DEFENCE SECRETARY OF STATE FOR 27 April 1970 [25 April 1969] 21219/69 Heading H3T A bi-stable circuit comprises a first pair of transistors T1, T2 having a common tail and their inputs and outputs cross-coupled, a second pair of transistors T7, T8 also having a common tail and having their output terminals connected to the input terminals of the first pair, means for supplying an input signal G between input terminals of the second pair, and means for switching current alternatively to the tail of the first pair or the tail of the second pair. The input signal is the output from a computer store, in which a " 1 is represented by a positive pulse followed by a negative pulse and a " 0 " by pulses in the opposite order. The tail switches S1 S2 are in fact a pair of transistors (T9, T10, Fig. 6, not shown) which are switched over by a periodic " clamp " signal. During this signal S1 is closed so that either T7 or T8 is made conducting according to the polarity of G, while S2 is open so that T1, T2 are in an unstable " both off " state. At the end of the clamp period, S1, S2 are switched over and T1, T2 assume a stable state corresponding to whichever of T7 or T8 was conducting at the instant of change over. Stray capacitance on the bases of T1, T2 retain the signal on T7, T8 during switch-over. In Fig. 6 emitter follower output transistors (T11, T12) are connected to the collectors of T1, T2, as also are " set " and " reset " transistor switches (T13, T14). In a " prior art " arrangement (Fig. 2, not shown) a single pair of transistors are switched to an unstable state by a shunting transistor (T3). This arrangement includes an adjustable resistor (RB) for balancing, and this circuit may be in integrated form.
