FSUSB42UMX-TP

This is a bidirectional, low-power, dual-port high-speed USB 2.0 analog switch with integrated protection, designed specifically for USB Type-C systems. The device is configured as a dual 2:1 or 1:2 switch, optimized for USB 2.0 DP/DM lines in USB Type-C systems. The device achieves true isolation — even when COM+/- exceeds VCC, only minimal current flows back to the supply. It features low inter-bit skew and high inter-channel noise isolation, and is compatible with high-speed USB 2.0 and other standards. Each switch is bidirectional with minimal or no attenuation of high-speed signals at the output. The bandwidth is wide enough to transmit high-speed USB 2.0 differential signals with excellent signal integrity.

Applications

• Mobile phones, tablets, and laptops
• Any application using USB Type-C or Micro-B connectors

Key features

• Low on-resistance: Ron = 1.5Ω at VCC = 5V
• 1.8V logic-compatible control pins
• High off-state isolation: -100dB @ 100KHz
• COM+/- rail extends to VCC, enabling true isolation even during power failure
• Low channel-to-channel crosstalk: -97dB @ 100KHz
• High bandwidth (-3dB @ 550MHz) for USB2.0 high-speed routing
• Low quiescent current (<2uA) with wide supply voltage range (1.5V ~ 5.5V)
