Triple 3-Input Positive-NAND Gates with Open-Collector Outputs
These devices contain three independent 3-input NAND gates with open-collector outputs. 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.
