Describe

The RLCS822 is a bidirectional low-power dual port, high-speed, USB 2.0 analog switch with integrated

protection for USB Type-C™ systems. The device is configured as a dual 4:1 or 1:4 switch. It is optimized for

use with the USB 2.0 DP/DM lines in a USB Type-C™ system.

The RLCS822 has low bit-to-bit skew and high channel-to-channel noise isolation, and is compatible with

various standards, such as high-speed USB 2.0 (480Mbps). Each switch is bidirectional and offers little or no

attenuation of the high-speed signals at the outputs. Its bandwidth is wide enough to pass high-speed USB 2.0

differential signals (480 Mb/s) with good signal integrity. The RLCS822 contains special circuitry on the

COM+/- pins which allows the device to withstand a VBUS short to USB 2.0 DP/DM lines when the USB

devices are either powered off or powered on. The AS3USB4000Q integrated over-voltage protection on the

COM+/- pins can withstand up to DC 30V with automatic shutoff circuitry in order to protect system

components behind the switch.

GPIO controls of S1/2 and _EN are 1.8V logic compatible. The RLCS822 is available in QFN 2.5x3.4-24L with

Pb-free and Halogen-free making it a perfect candidate for mobile and space constrained applications.
