Choose the correct alternatives (More than one may be correct).
Two NAND gates having open collector outputs are tied together as shown in below figure.
The logic function Y, implemented by the circuit is,
Correct Answer: E
Question 27 Explanation:
There should be bubbled connection between two gates
Y = ((ABC)’ + (DE)’)’
Y = ABC . DE
Note: Open gate works as NOR gate.
Y = ((ABC)’ + (DE)’)’
Y = ABC . DE
Note: Open gate works as NOR gate.
Y = ABC + DE
Y = ABC . DE
Both (C) and (D)
