MCHPUSB3740B-AI2-TR
Overview
The USB3740B-AI2-TR is a high-speed USB 2.0 switch designed to multiplex USB data between two different ports or functions. It utilizes Microchip flexPWR technology to achieve extremely low power consumption, drawing as little as 30uA in standby and active modes. This makes it an ideal solution for power-sensitive portable devices that require flexible USB connectivity without sacrificing battery life.
Why Choose This Part
This switch offers a high bandwidth of 1GHz, ensuring excellent signal integrity for USB 2.0 High Speed (480Mbps) data rates. The ultra-small 1.3mm x 1.8mm 10-UQFN package saves critical PCB real estate, while the 5V tolerant I/O and wide supply range of 1.8V to 5V simplify integration into various voltage domains.
Applications
Key Specifications
Getting Started
To evaluate this switch, ensure your PCB layout maintains 90-ohm differential impedance for USB data pairs and keep traces as short as possible to utilize the 1GHz bandwidth. Since it is a passive mux, no software drivers are required, but designers should verify that the select (SEL) pin logic levels match the system microcontroller's GPIO voltage.
