आउटपुट समीकरण:

महत्त्वाचे मुद्दे:

1) A नेहमी उच्च असल्यास, आउटपुट हे इतर इनपुट B चे उलटे मूल्य असते, म्हणजे B̅

2) जेव्हा दोन्ही इनपुट जास्त असतात तेव्हाच आउटपुट कमी होते

3) हे एक सार्वत्रिक द्वार आहे

सत्य सारणीतून जेव्हा A = B = 0,  NAND आणि NOR गेटसाठी आउटपुट Y = 1 

तसेच जेव्हा A = B = 1, NAND आणि NOR गेटसाठी आउटपुट Y = 0
