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 SN54ABT241,

SN74ABT244A, 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.

The SN54ABT240 and SN74ABT240A are organized as two 4-bit buffers/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.

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 SN54ABT240 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74ABT240A is characterized for operation from –40°C to 85°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
