It isolates or connects digital buses under logic control, commonly used in hot-swap backplanes, memory bank switching, or multi-master I2C/SPI lines where capacitive loading must be decoupled. Supplied in a 20-pin QSOP (0.154-inch body width, 3.90 mm) — a narrower variant of the standard SOIC footprint. The 20-QSOP land pattern matches the JEDEC MO-137 variation; the 0.025-inch pitch requires a fine-pitch soldering profile but fits within a 4-layer board fan-out without micro-vias.","metaTitle":"Renesas QS3244QG Bus Switch, 4 x 1:1, 20-QSOP","metaDescription":"Renesas QS3244QG bus switch, 4 x 1:1 circuit, 4.75V-5.25V supply, -40°C to 85°C, 20-QSOP.
