I am using 74LS112N JK flip flop, and i'm giving 5 volts to the circuit using 7805, which becomes extremely hot, when the circuit works. I have connected 0(GND) to CLR, K=0,J=1 CLK=1, PRcomplement=1, what could be the problem? When I give an i/p of 12V, the i/p that reaches 7805 is just 3.8, and also it becomes unbearably hot..
