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. The ’HC240 are organized as two

4-bit buffers/drivers with separate output-enable

(OE) inputs. When OE is low, the device passes

inverted data from the A inputs to the Y outputs.

When OE is high, the outputs are in the

high-impedance state.
