251M-21LFT

Overview

The QS3VH251QG8 is a 3.3V 8:1 multiplexer/demultiplexer manufactured by Renesas Electronics Corporation, belonging to the QS3VH251 series. It is housed in a QSOP-16 package and classified under Encoders, Decoders, Multiplexers & Demultiplexers within Logic ICs. The component supports Reel, Cut Tape, and MouseReel packaging formats. It operates with a supply voltage range typical for 3.3V logic applications and features RoHS compliance. The device weighs approximately 288 mg and is identified by part number aliases including IDTQS3VH251QG8.

Feature Summary

Configurable as an 8:1 multiplexer or demultiplexer
Operates at 3.3V supply voltage
Available in QSOP-16 surface mount package

Applications

Data routing in digital systems
Signal selection in communication interfaces
Logic level translation circuits

Procurement Notes

Verify the specific ordering suffix QG8 against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Confirm RoHS status and moisture sensitivity levels prior to assembly. Check for any process change notices (PCN) that may affect pinout or electrical characteristics. Ensure compatibility with existing PCB footprint designs for QSOP-16 packages.

Selection Notes

Select this component when an 8-channel signal selector is required for 3.3V logic families. Verify input/output voltage tolerances match the system requirements. Consider the QSOP-16 package constraints regarding board space and thermal dissipation. Compare propagation delay and on-resistance parameters if high-speed switching is critical for the application design.

Part Context

This part belongs to the QS3VH251 family of high-speed CMOS multiplexers. It serves as a replacement for legacy IDT QS3VH251 devices following the acquisition of Integrated Device Technology by Renesas Electronics. The component is categorized under general-purpose logic switches used for data path management in embedded systems.

Replacement Considerations

Direct substitutes include the IDTQS3VH251QG8. Verify pin compatibility and electrical specifications before substituting with other 8:1 muxes from different manufacturers.
