NTE74LS05 Integrated Circuit TTL − Hex Inverter with Open Collector Outputs Description: The NTE74LS05 contains six independent inverters in a 14−Lead plastic DIP type package. The open collector outputs require pull−up resistors to perform correctly. They may be connected to other open collector outputs to implement active−low wired−OR or active−high wired−AND functions. Open collector devices are often used to generate higher VOH levels.
