description
These devices contain four independent 2-input
NAND gates. They perform the Boolean functions
Y = A•B or Y = A+B in positive logic. The
open-collector outputs require pullup resistors to
performcorrectly. Theymaybeconnectedtoother
open-collector outputs to implement active-low
wired-OR or active-high wired-AND functions.
Open-collector devices are often used to generate
