SN74HC244N General Description
The SN74HC244N is a specialized octal buffer and line driver that is specifically engineered to optimize the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. It comprises two 4-bit buffers and drivers with separate output-enable (OE) inputs, allowing for seamless data transfer and control. When the OE is low, it allows noninverted data from the A inputs to be transmitted to the Y outputs, while a high OE places the outputs in a high-impedance state. This level of precision and flexibility makes the SN74HC244N a valuable asset for a variety of electronic applications
