what do u mean verify theVerify the lead diagram of the 2N2222 transistor. There are two different pin-outs.
Verify the lead diagram of the 2N2222 transistor. There are two different pin-outs.
What voltages are you seeing at input pins 2 and 3 of the 7382?
i am able to obtained the output. its due to the grounding error.What voltage do you get at pin 6 of the 6N137?
Is pin 5 of the 6N137 properly grounded?
Try increasing RL to at least 1kΩ.
