description
These devices contain six independent hex
inverters with open-collector outputs. They
perform the Boolean function Y = A. The
open-collector outputs require pullup resistors to
perform correctly. These outputs can 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.
