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 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-W 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 –55°C to 125°C.

The SN74ABT2241 is characterized for operation from –40°C to 85°C.
