Analog Switches - Special Purpose datasheet and documents for FSUSB42UMX

FSUSB42UMX

Analog Switches - Special Purpose Overview

The FSUSB42UMX is a bi-directional, low-power, two-port, high-speed USB 2.0 switch configured as a double-pole, double-throw (DPDT) device. It operates on a single supply voltage ranging from 2.4 V to 4.4 V and supports data rates up to 480 Mbps. The component features a typical on capacitance of 3.7 pF and a -3 dB bandwidth exceeding 720 MHz. Maximum on resistance is specified at 7.5 ohms across the operating temperature range of -40°C to +85°C. It is housed in a 10-lead UMLP package measuring 1.4 x 1.8 mm.

Analog Switches - Special Purpose Feature Summary

Ultra-low power consumption with maximum quiescent current of 1 µA
High signal integrity through wide bandwidth and minimal channel crosstalk
Robust over-voltage tolerance on all USB ports without external components
Direct interface capability with baseband processor general-purpose I/Os

Analog Switches - Special Purpose Applications

Portable cell phones and PDAs
Digital cameras and notebook computers
LCD monitors, TVs, and set-top boxes

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix UM for the UMLP package configuration when sourcing. Confirm that the selected variant matches the required lead frame and marking specifications defined in the official datasheet. Ensure compliance with RoHS directives and moisture sensitivity level requirements during storage and handling procedures.

Analog Switches - Special Purpose Selection Notes

Select this component for designs requiring compact footprint and low power dissipation in portable electronics. Verify that the control voltage levels are compatible with the host processor's GPIO outputs. Consider the break-before-make timing characteristics for applications involving hot-swapping or rapid source switching between high-speed and full-speed interfaces.

Analog Switches - Special Purpose Part Context

This part belongs to the FSUSB42 series of USB switches manufactured by onsemi. It serves as a multiplexer for routing differential USB data lines between multiple sources. The UM suffix specifically denotes the 10-lead Ultrathin Molded Leadless Package (UMLP), distinguishing it from other package options like MSOP within the same functional family.
