MAXIM INTEGRATED / ANALOG DEVICES MAX14978ETO High-Speed USB Switch
The MAX14978ETO+ is a high-performance, passive analogue switch designed for high-speed and SuperSpeed USB applications. It features 42 pins in a TQFN package and supports data switching for USB low speed, full speed, high speed, and SuperSpeed signals. Operable from a single 3.3V supply, it offers low insertion loss, high return loss, and minimal distortion, making it ideal for applications where multiple USB ports are limited. The device includes two sets of analogue switches—one for USB low, full, and high-speed signals, and the other dedicated to SuperSpeed data—allowing efficient switching between multiple loads. It provides excellent ESD protection with ±6KV HBM on all I/O pins, and enhanced protection of ±15KV HBM and ±8KV IEC 61000-4-2 for specific ports. Additional features include low supply current (0.6 µA at 3V and 60 µA at 3.3V), off isolation of -48 dB, crosstalk of -73 dB at 10 MHz, and strong link training preservation over LVCMOS control (1.4V to 3.6V). The switch operates across a temperature range from -40°C to 85°C, with maximum on-resistance of 10 ohms for high-speed USB switching. It is suitable for signal processing, industrial, and portable device applications.
