The MC74HC05A contains six inverters with open drain outputs. The MC74HC05A is identical to the MC74HC04A, except for the open drain outputs. The outputs can be connected to other open drain outputs to implement active LOW wired−OR or active High wired−AND logic functions. The open drain outputs require pull−up resistors to perform correctly.
