TheUSB5742Bversion contains the latest silicon. All new USB5742 designs should move to this newer "B" version.
Microchip’s USB5742 SmartHub™ IC is a 2 port, SuperSpeed (SS)/Hi-Speed (HS), low power, low pin count configurable and fully compliant with the USB 3.2 Gen 1 specification. The USB5742 also supports Full Speed (FS) and Low Speed (LS) USB signaling, offering complete coverage of all defined USB operating speeds. The new SuperSpeed hubs operate in parallel with the USB 2.0 controller, so 5 Gbps SuperSpeed data transfers are not affected by slower USB 2.0 traffic.
The USB5742 is in a 0.4mm pitch, 56 pin QFN. It's the smallest 2 port USB 3.2 Gen 1 hub in the industry. Functionality was reduced to optimize pin count and provide a cost effective solution.
SmartHub ICs are defined as a USB hub that integrates system levels functions typically associated with a separate MCU or processor. Microchip’s USB5742 Smart Hub support custom configurations of external ports and GPIO pins. MPLAB Connect Configurator, Microchip’s proprietary software utility, can be used to program On-chip One Time Programmable (OTP) ROM which stores required register settings to ensure the desired start up configuration at power on. All port control signal pins and GPIOs are under firmware control, allowing for maximum operational flexibility. However, for even more simplicity, the USB5742 can be configured through a series of external low-cost resistor bootstraps. No OTP programming required.

YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
USB5742 is an authentic electronic component manufactured by Microchip, categorized under Interface ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official USB5742 datasheet above.
Electronic component spot-market pricing for USB5742 fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for USB5742 depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
