Taken together with the AC11240 and AC11244, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical G (activelow output control) inputs, and complementary G and G inputs. This device features a high fan-out. The 54AC11241 is characterized for operation over the full military temperature range of – 55°C to 125°C. The 74AC11241 is characterized for operation from – 40°C to 85°C. 54AC11241 . . .
