OCTAL BUFFERS AND LINE/MOS DRIVERS WITH 3-STATE OUTPUTS

These octal Buffers and Line Drivers SN54BCT2240 SN74BCT2240 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 SN74BCT2241 and BCT2244, 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 is 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. The outputs, which are designed to source or sink up to 12 mA, include 33- series resistors to reduce overshoot and undershoot. The SN54BCT2240 is characterized for operation over the full military temperature range of 55C to 125C. The SN74BCT2240 is characterized for operation from 0C to 70C By Texas Instruments
