Describe
The RLCS7222 is a bidirectional, low-power, high-speed USB 2.0 analog switch designed for USB
Type-C™ systems. Configured as a dual 2:1 or 1:2 switch, it supports USB 2.0 DP/DM lines with
true isolation, minimizing backflow current even when COM+/- overrides VCC.Featuring low skew,
high noise isolation, and wide bandwidth, it ensures signal integrity for high-speed USB 2.0 (480
Mbps) with minimal attenuation. The switch is bidirectional and compatible with multiple standards.
Controlled via 1.8V GPIO logic (SEL pin), the RLCS7222 comes in compact QFN (1.4x1.8-10L)
and MSOP-10L packages, making it ideal for mobile and space-constrained applications. It is
Pb-free and halogen-free.
Low On-Resistance (Ron): 1.5Ω (VCC = 5V)
1.8V Logic Control: GPIO-compatible SEL pin
True Isolation: COM+/- overrides VCC, ensuring isolation even with dead supply
High Off-Isolation: -100dB @ 100kHz
Low Crosstalk: -97dB @ 100kHz
High Bandwidth: -3dB @ 800MHz, ideal for USB 2.0 High-Speed (480Mbps)
Ultra-Low Power: <2µA quiescent current (1.5V–5.5V supply range)
Anywhere a USB Type-C™ or Micro-B Connector is Used
Mobile Phones
Tablets and Notebooks
