General description
The 74HC05 is a high-speed Si-gate CMOS device that complies with JEDEC standard
no. 7A.
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-LOWwired-OR or active-HIGH
wired-AND functions. The open-drain outputs require pull-up resistors to perform correctly.
