Your topic and the question you're askin doesn't fit together. Please rephrase your question or make two different threads instead.

And when you asking about a schematic, you need to either link to it or upload it.

The circuit appears to work perfectly.

You forgot to say what your circuit does:
Are all the LEDs turned on all the time?
Are only half of the LEDs lighted?
Do none of the LEDs light?

There is a slight difference between the LM3914, and the LM3914N-1. The N-1 is in a slightly longer package and pins 1,18 and 9,10 are different shape than the same pins on the LM3914. See the attachments. As far as I can tell they both work the same. The LM3914 has been discontinued, and is actually more expensive at some distributors.
