Product Summary

The SN74HCT244NSR is an octal buffer and line driver. It is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receiver and transmitter. The SN74HCT244NSR 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.
