SN54F244, SN74F244 is an octal buffer/driver with 3-state outputs produced by Texas Instruments. It can drive bus lines or buffer memory address registers. The device is available in plastic small-outline (SOIC) and shrink small-outline (SSOP) packages, ceramic chip carriers, and plastic and ceramic DIPs.
The SN54F244 and SN74F244 are octal buffers and line drivers designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. These devices feature separate output enable (OE) inputs for each buffer, allowing data to pass from A inputs to Y outputs when OE is low, while outputs enter a high-impedance state when OE is high.
The SN54F244 is characterized for operation over the full military temperature range of -55°C to 125°C.
The SN74F244 is characterized for operation from 0°C to 70°C.
