Question

Latches constructed with NOR and NAND gates tend to remain in the latched condition due to which configuration feature?

(a) Low input voltages

(b) Synchronous operation

(c) Gate impedance

(d) Cross coupling

I had been asked this question in examination.

I would like to ask this question from Flip Flops topic in chapter Flip-Flops of Digital Circuits

Answer 1

The correct option is (d) Cross coupling

The explanation is: Latch is a type of bistable multivibrator having two stable states. Both inputs of a latch are directly connected to the other’s output. Such types of structure is called cross coupling and due to which latches remain in the latched condition.
