description

These octal buffers and line drivers are designed

specifically to improve the performance and

density of 3-state memory address drivers, clock

drivers, and bus-oriented receivers and

transmitters.

The ’AC240 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.
