SN54BCT2240, SN74BCT2240 OCTAL BUFFERS AND LINE/MOS DRIVERS WITH 3-STATE OUTPUTS SCBS030E − SEPTEMBER 1988 − REVISED MARCH 2003 D Operating Voltage Range of 4.5 V to 5.5 V D State-of-the-Art BiCMOS Design Significantly Reduces ICCZ D Output Ports Have Equivalent 33-Ω Series Resistors, So No External Resistors Are Required D 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers description/ordering information 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. Together with the SN74BCT2241 and the ’BCT2244 devices, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical active-low output-enable (OE) inputs, and complementary OE and OE inputs. These devices feature high fan-out and improved fan-in. The ’BCT2240 devices are organized as two 4-bit line drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state. SN54BCT2240 . . . J OR W PACKAGE SN74BCT2240 . . .
