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 SN54ABT240,

SN74ABT240A, and ’ABT244A, 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.

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. 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 SN54ABT241 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74ABT241A is characterized for operation from –40°C to 85°C.

PRODUCTION DATA information is current as of publication date.
