Describe

The RLCS3340 is a high-speed bidirectional passive switch for USB Type-C™ applications,

supporting USB 3.1 Gen 1/2 data rates. Controlled by the SEL pin, it switches differential channels

between Port L0/L1 and Port C0. It’s a generic analog switch for high-speed interfaces with a 0 to

2V common mode range and up to 1.8Vpp differential amplitude. Adaptive tracking maintains

channel integrity across the common mode range. Its dynamic performance ensures minimal signal

attenuation and jitter. Power consumption is <2mW (operational) and <20µW (shutdown via _EN

pin). Available in QFN 2x3-18L and QFN 3x3-16L (Pb-/Halogen-free), it’s ideal for mobile and

space-constrained designs.
