Texas Instruments 20-SOIC SN74HC540DWG4

The SN74HC540DWG4 is a Texas Instruments-manufactured digital integrated circuit in the 74HC540 family. It's an octal buffer/line driver designed for high-speed operation with low power consumption, featuring non-inverting buffers in a DIP or SMD package (DWG4 denotes a specific surface-mount packaging variant). The device provides eight independent buffers to amplify and isolate signals, ensuring proper signal integrity across multiple circuits. Each buffer has three-state outputs allowing them to be connected directly to buses. Its logic levels comply with HC (High-Speed CMOS) standards, operating at a voltage range of typically 2V to 6V. For detailed specifications, consult the manufacturer's datasheet.
