Q1:

If both inputs of an S-R NAND latch are LOW, what will happen to the output?

A The output would become unpredictable.

B The output will toggle.

C The output will reset.

D No change will occur in the output.

ANS:A - The output would become unpredictable.

NAND Gate is active low.

Its provide the output excitedly reverse of NOR gate.

In NOR Gate when i/p is 00 output is No CHANGE but i/p is 11 its unpredictable, so it reverse in NAND Gate.
