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 ’HC244 are organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the device passes noninverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.The SN54HC244 is characterized for operaTIon over the full military temperature range of –55°C to 125°C. The SN74HC244 is characterized for operaTIon from –40°C to 85°C.
