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 ′ABT2240

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 25-Ω series resistors to reduce

overshoot and undershoot.

To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN74ABT2244 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count

and functionality of standard small-outline packages in less than half the printed-circuit-board area.

The SN54ABT2244 is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74ABT2244 is characterized for operation from –40°C to 85°C.
