缓冲器和线路驱动器 Tri-State Octal /MOS
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 SN54ABT2240, SN74ABT2240A, and "ABT2241, 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.
When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, 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.
The SN54ABT2244A is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT2244A is characterized for operation from -40°C to 85°C.
