16-bit bus driver from the LVC/LCX/Z family
The 74LVC16240ADGG-Q100653 is a 16-bit bus driver from the LVC/LCX/Z series, designed for high-speed, low-voltage bus interfacing in digital systems. It buffers and drives address/data lines with the characteristic low-noise, high-drive output of the LVC logic family, making it a standard choice for memory-mapped I/O and backplane buffering in industrial and automotive control boards.
Package and mounting
The actual package is a TSSOP-48 (the ADGG suffix), which is a fine-pitch surface-mount footprint. On the rework bench, that means hot-air reflow with a fine nozzle and preheating the board from the bottom to avoid tombstoning. MSL is typically 1 for LVC parts, but check the bag label — if it has been open past the floor-life window, a 24-hour bake at 40 °C is the safe move before reflow.
