description/ordering information

This octal buffer and line driver is designed specifically to improve both the performance and density of 3-state

memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The SN74HCT244 device

is 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.
