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,
A Wired Connection can create both an AND gate and an OR gate , however it cannot implement a not gate .
but to know whether this intersection acts as AND gate or OR gate , we should know whether the intersection is at a HIGH or a LOW.
i think here they have assumed it to be at a HIGH , hence the answer will be Y=(ABC)' . (DE)' .
There should be bubbled connection b/w two gates
y=((ABC)' + (DE)' )'
NOTE: open gate works as NOR gate.
