Bistable MultivibratorsThe circuitBistable multivibrators have the property being able to maintain one of two possible states. Though similar to Schmitt triggers, they differ in that the changing of states is evoked by subsequent and equally shaped trigger pulses. These so-called flip-flops are the basic memory blocks for binary signals. The following is a simple latch flip-flop. It consists of four NAND gates. When the clock input is set to T = 1, the binary variable, D, at the delay input is shifted to the output, Q. If clock input is set to T = 0, the output, Q, is isolated from D. The latch may be realised with OR gates as well. The described functionality will then arise when clock signal is inverted.
