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 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.
The SN54HC240 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74HC240 is characterized for operation from -40°C to 85°C.
