• 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers • Package Options Include Plastic Small-Outline Packages, Ceramic Chip Carriers, and Plastic and Ceramic DIPs description These octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. Taken together with the ′F240 and ′F244, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical OE (active-low output-enable) inputs, and complementary OE and OE inputs. The SN54F241 is characterized for operation over the full military temperature range of – 55°C to 125°C. The SN74F241 is characterized for operation from 0°C to 70°C.
