Product Details
Key Features
Documentation

The MIC74 is a fully programmable serial-to-parallel I/O expander compatible with the SMBus™ (system management bus) protocol. It acts as a "slave" on the bus, providing eight independent I/O lines.

Each I/O bit can be individually programmed as an input or output. If programmed as an output; each I/O bit can be programmed as an open-drain or complementary push-pull output. If desired, the four most significant I/O bits can be programmed to implement fan speed control. An internal clock generator and state machine eliminate the overhead generally associated with "bit-banging" fan speed control.

Programming the device and reading/writing the I/O bits is accomplished using seven internal registers. All registers can be read by the host. Output bits are capable of directly driving high-current loads such as LEDs. A separate interrupt output can notify the host of state changes on the input bits without requiring the MIC74 to perform a transaction on the serial bus or be polled by the host.

Three address selection inputs are provided, allowing up to eight devices to share the same bus and provide a total of 64 bits of I/O.

The MIC74 is available in an ultra-small-footprint 16-pin QSOP. Low quiescent current, small footprint, and low package height make the MIC74 ideal for portable and desktop applications.

YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.

  • 1. Certification Scope: Quality certifications apply only to the entities, sites and activities listed in valid certificates. Management system certification does not certify each individual product.
  • 2. Product Authenticity: Products must match the agreed manufacturer, part number and condition. Supplier screening and authenticity checks help reduce counterfeit risk.
  • 3. Inspection & Testing: The inspection scope follows product risks and agreed requirements. Additional testing, laboratory arrangements, costs and lead times require written confirmation.
  • 4. Traceability & Documentation: Request conformity certificates, traceability records or test reports before ordering. Document availability, issuer and coverage must be confirmed for the offered goods.
  • 5. Environmental Compliance: RoHS and REACH information is based on applicable manufacturer documentation. Confirm the exact part, declaration date and relevant exemptions before ordering.
  • 6. Handling & Protection: Handling, storage and packaging follow applicable product requirements, including ESD and moisture protection where required. Special handling requirements must be agreed before ordering.

Product FAQ
Purchasing FAQ

What type of component is MIC74, and what package does it use?

MIC74 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 MIC74 datasheet above.

Why is dynamic quotation used instead of a fixed price for MIC74?

Electronic component spot-market pricing for MIC74 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.

What is the delivery timeline after placing an order for MIC74?

Lead times for MIC74 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.
