The QS3VH800QG is a 10-bit bus switch from Renesas, organised as 10 independent 1:1 switches in a single 24-QSOP package.
What the 10 x 1:1 circuit means on a board
The 10 independent 1:1 switches let ten separate signal lines pass through the device, each switched on or off by a common enable. In a typical multiplexed bus or hot-swap backplane, this replaces ten discrete FETs or a larger crosspoint switch.
Package and board-fit: 24-QSOP vs 24-SSOP
The QS3VH800QG comes in a 24-QSOP package (supplier device package), which is the same 3.90 mm-wide body as the 24-SSOP footprint but with a finer lead pitch. The 0.154-inch (3.90 mm) width means it fits on a standard 0.65 mm-pitch SSOP land pattern — no board respin if you are replacing a 24-SSOP bus switch. Surface-mount only; no socket option for field swap without a hot-air station.
Active production, ROHS3 compliant
Renesas lists the QS3VH800QG as Active (current production) and ROHS3 Compliant.
