The SN74HC05N is a 1-input 14-pin Hex Inverter made of CU NIPDAU lead/ball finish. The device contains six independent inverters. It performs the Boolean function Y = A in positive logic. The open-drain outputs require pull-up resistors to perform correctly. It may be connected to other open-drain outputs to implement active-low wired-OR or active-high wired-AND functions.
