A logic circuit which retains whatever output state results from a momentary input signal until the application of a different signal to the same input point or the same signal to a different point. Also  latch circuit.

M. Grabbe  et al.  Handbk. Automation, Computation, & Control II. xvii. 6  				A delay element is provided with external gating which enables it to hold information provided on the ‘set’ input until a ‘reset’ input of 1 occurs. This configuration..is sometimes referred to as a latch. 1962    J. H. Simpson  & R. S. Richards Physical Princ. Junction Transistors xvi. 403  				A variant of it [sc. the ‘flip-flop’], known as the latch, is an asymmetric bistable multivibrator. 1971    J. H. Smith Digital Logic iv. 54  				A push button might be pressed and at a certain time in a machine sequence the fact that the button was pressed may be needed to change the sequence. The latch circuit is therefore used to ‘remember’ that a push button has been pressed. 1971    J. H. Smith Digital Logic iv. 54  				A 1 signal applied momentarily to the set input of NOR 1 will make O/P1 a 0 signal... To reset the latch a 1 signal is fed to the reset input which makes O/P2 fall to 0. As NOR 1 no longer has a 1 input, O/P1 changes to 1, thereby holding O/P2 at the 0 level. < as lemmas  |
