positive-AND gates. They perform the Boolean
鈥?/div>
B or Y = A + B in positive logic.
The open-collector outputs require pullup
resistors to perform correctly. These outputs 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 V
OH
levels.
The SN54ALS09 is characterized for operation
over the full military temperature range of 鈥?55擄C
to 125擄C. The SN74ALS09 is characterized for
operation from 0擄C to 70擄C.
