Home > Industry Information > FSUSB74MPX: Low-Power And High-Performance USB 2.0 Multiplexer
The FSUSB74MPX is a bidirectional, low-power, high-speed USB 2.0 4:1 multiplexer launched by ON Semiconductor. It can switch from four high-speed (480Mbps) sources
or any combination of high-speed and full-speed/low-speed (12Mbps) USB/UART sources to a USB 2.0 connector.
Working voltage: 2.5V to 4.4V
On-resistance (maximum value) : 9Ω
Operating temperature: -40℃ to +85℃
Package form: 16-WFQFN (3x3mm), with exposed pads
Number of channels :1 4:1 channel
Feature: Break Before Make, compatible with USB 2.0.
· On-resistance: The maximum on-resistance is only 9Ω. Low on-resistance can significantly reduce the loss during signal transmission, improve signal integrity and transmission efficiency,
and also help lower the heat generation of the chip, enhancing the stability and reliability of the system.
· Broken-before-Make function: When switching channels, disconnect the current connection first and then establish a new one.
This feature can effectively avoid signal conflicts and ensure the integrity of the signal and the security of the device.
· Electrostatic Discharge (ESD) protection: Compliant with IEC61000-4-2 standard, capable of withstanding 15kV air discharge and 8kV contact discharge.
This enables the FSUSB74MPX to maintain stable operation in various harsh environments, avoiding the impact on the reliability of the equipment due to static damage.
· Compatible with full-speed and low-speed USB: In addition to the high-speed mode, the FSUSB74MPX is also compatible with full-speed (12 Mbps) and low-speed (1.5 Mbps) USB/UART signals.
This wide compatibility enables it to seamlessly integrate with USB devices of various speeds.
The FSUSB74MPX is capable of selecting one signal from four high-speed (480 Mbps) or full-speed/low-speed (12 Mbps) USB/UART sources for output to a USB 2.0 interface.
This feature makes it highly suitable for use in USB hubs or application scenarios where switching between multiple USB devices is required.
In embedded systems, the low power consumption (typical operating current 9μA) and compact package (16-WFQFN, 3x3mm) of the FSUSB74MPX make it an ideal choice.
It can achieve efficient signal switching within a limited space while reducing system power consumption.
Multiplexers play an important role in data acquisition systems and sensor networks. The FSUSB74MPX can be used to switch signals from multiple sensors to a single USB interface,
thereby achieving efficient data acquisition and transmission.
In communication systems, the FSUSB74MPX can be used to merge multiple data streams into one channel, thereby enhancing bandwidth utilization.
Its high-speed switching capability ensures the efficiency of data transmission.
As a high-performance USB 2.0 4:1 multiplexer, FSUSB74MPX has demonstrated outstanding application value in multiple fields such as USB hubs, embedded systems, multimedia devices, industrial control,
and portable devices, thanks to its characteristics of low power consumption, high-speed data transmission, high reliability, and compact packaging. Its wide compatibility and flexible signal switching capability
make it an indispensable key component in modern electronic systems.
