Product details

What this bus switch does on the board

The Renesas QS3VH257S1G8 is a 4 x 2:1 bus switch from the 3VH series. It runs on a single 2.3V to 3.6V supply. Four independent 2:1 mux/demux channels mean you can swap between two data sources — say, a primary and backup SPI flash — or share one ADC input across two analog front-ends.

The 16-SOIC (0.154", 3.90mm width) body is a standard surface-mount footprint. The Tape & Reel and Cut Tape options cover both prototype and production runs.

ROHS3 compliance is confirmed. It clears the EU RoHS directive without an exemption claim.

Frequently asked questions

Is QS3VH257S1G8 RoHS compliant?

Yes, it is ROHS3 compliant, meeting the latest EU RoHS directive including the four phthalates.

What is the equivalent part for QS3VH257S1G8?

The QS3VH257PAG is the same 4 x 2:1 bus switch from the same 3VH series, but in a different package and tube delivery. The S1G8 suffix indicates the 16-SOIC package on tape and reel; the PAG variant is a different package. For a direct footprint and function match, stick with the S1G8 suffix.
