description
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 ’ABT2241 and
’ABT2244A, these devices provide 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.

These devices are organized as two 4-bit line drivers with separate OE inputs. When OE is low, the devices pass
inverted 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 sink up to 12 mA, include equivalent 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_CC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54ABT2240A is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74ABT2240A is characterized for operation from –40°C to 85°C.
