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.
