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. Taken together with the ′F241 and

′F244, these devices provide the choice of

selected combinations of inverting and

noninverting outputs, symmetrical OE (active-low

output-enable) inputs, and complementary OE

and OE inputs.

The ′F240 is organized as two 4-bit buffers/line

drivers with separate output enable (OE) inputs.

When OE is low, the device passes data from the

A inputs to the Y outputs. When OE is high, the

outputs are in the high-impedance state.

The SN74F240 is available in TI’s shrink

small-outline package (DB), which provides the

same I/O pin count and functionality of standard

small-outline packages in less than half the

printed-circuit-board area.

The SN54F240 is characterized for operation over

the full military temperature range of –55°C to

125°C. The SN74F240 is characterized for

operation from 0°C to 70°C.
