<p>1461443 Bistable circuits SONY CORP 1 Feb 1974 04901/74 Heading H3T A bistable multivibrator comprises first and second bistable stages 1, 2 intercoupled via a steering gate circuit 3; first and second clock input circuits 16, 17 for isolating nodes 23, 24 so as to enable the bistable stage 1 and the steering gate 3 to be actuated independently so as to assure correct triggering by a clock signal. Circuit 17 may preferably be biased to turn on and turn off ahead of circuit 16. The clock pulses serve to periodically enable and disable the master bistable stage 1 and the steering gate 3. In the turned off state, transistors 13, 14 are effectively equivalent to base collector diodes with a threshold voltage Vbc. The conduction states of the transistors 5, 6 in the master bistable 1 and of transistors 7, 8 in the slave bistable 2 are periodically altered in dependence of the base potentials existing of steering gate transistors 14, 13.</p> |
