2 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.

The ’HC240 devices 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.
