Electronic Devices Question 281
The output of a NAND gate is 1 when both inputs are 1
[UPSEAT 2004]
Options:
A) If both inputs are zero
B) If one input is 0 and the other input is 1
C) If both inputs are 1, the output is 1
D) Either if both inputs are 1 or if one of the inputs is 1 and the other is 0
Show Answer
Answer:
Correct Answer: C
Solution:
If inputs are A and B then output for NAND gate is $ Y=\overline{AB} $
Therefore If $ A=B=1 $ , $ Y=\overline{1}=\bar{1}=0 $
