The 74HC05 contains six inverters. The outputs of the 74HC05 are open-drain and can be connected to other open-drain outputs to implement active-LOW wired-OR or active-HIGH wired-AND functions. The open-drain outputs require pull-up resistors to perform correctly.
Package Includes :
1 x 7405 (74HC05) Hex Inverter 6 Channel Open Collector IC
