Product Summary

The SN74AHCT244QDWRQ1 is an octal buffer/driver. The SN74AHCT244QDWRQ1 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 SN74AHCT244QDWRQ1 is organized as two 4-bit buffers/line drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.
