There are 2 ways to use 2 input nand gates as a inverter. I know one of them, which is make 2 inputs connected to one input signal.

Can someone tell me another one?

  • \$\begingroup\$ Yeah, fair enough @WhatRoughBeast. I considered both but looking back it's a logic question, not an implementation/circuit question. \$\endgroup\$
