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,

SN74ABT241A, SN54ABT244, and

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.
