अवधारणा:
NAND द्वार
प्रतीक:
सत्यमान सारणी:
|
निवेश A |
निवेश B |
निर्गम \(Y = \overline {AB}\) |

0 |
निर्गम समीकरण: \(Y = \overline {A.B} = \overline A + \overline B\)
प्रमुख बिंदु:
1) यदि A हमेशा उच्च होता है, तो निर्गम अन्य निवेश B का उल्टा मान होता है, अर्थात B̅
2) निर्गम कम तभी होता है जब दोनों निवेश अधिक हों
3) यह एक सार्वभौमिक द्वार है

जब सत्यमान सारणी से A = B = 0, NAND और NOR गेट के लिए निर्गम Y = 1
साथ ही जब A = B = 1, NAND और NOR द्वार के लिए निर्गम Y = 0
