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

These octal Buffers and Line Drivers SN54ABT2241 SN74ABT2241 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 SN54ABT2240, SN74ABT2240A and ABT2244A, 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 outputs, which are designed to sink up to 12 mA, include equivalent 25- series resistors to reduce overshoot and undershoot. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. The SN54ABT2241 is characterized for operation over the full military temperature range of 55C to 125C. The SN74ABT2241 is characterized for operation from 40C to 85C. By Texas Instruments
