description
ThIs octal buffer or line driver is designed specifically to improve both the performance and density of 3-state
memory address drivers, clock drivers, and bus-oriented receivers and transmitters. Together with the
鈥橝CT11240, this device provides the choice of various combinations of inverting and noninverting outputs.
The 74ACT11244 is characterized for operation from 鈥?0擄C to 85擄C.
