IDTQS3390SOG8

Overview

The IDTQS3390SOG8 is a single multiplexer/demultiplexer integrated circuit manufactured by Renesas Electronics Corporation. It features a 16-to-8 configuration housed in a 28-pin QSOP package. The device operates on a single power supply with a voltage range of 4.75V to 5.25V. It supports an operating temperature range from -40°C to +85°C and utilizes surface-mount installation. This component belongs to the QS3390 basic product family.

Feature Summary

• Functions as a signal routing multiplexer or demultiplexer for digital logic applications
• Supports asynchronous switching between input and output channels
• Designed for standard CMOS logic interface compatibility

Applications

• Digital signal routing in computer systems
• Data bus expansion architectures
• Peripheral interface management

Procurement Notes

Verify component authenticity through authorized distributors, as this part is officially listed as obsolete. Confirm package integrity upon receipt, noting the specific 28-QSOP form factor. Check datasheet revisions for any historical process changes documented in Product Change Notifications prior to final design implementation.

Selection Notes

Select this component only if legacy system compatibility with the 16:8 MUX/DEMUX topology is required. Ensure the design accommodates the 4.75V to 5.25V single-supply constraint. Verify that the 28-QSOP footprint matches the existing PCB layout, as alternative packages may require schematic and board redesign.

Part Context

This device is part of the QS3390 series, which provides high-speed multiplexing solutions. The manufacturer transitioned from IDT branding to Renesas Electronics. The 'SOG8' suffix typically denotes the specific 28-SSOP/QSOP package variant and lead-free compliance status within the broader product line.

Replacement Considerations

Consult official Product Change Notifications (PCN) for qualified substitute part numbers. Direct pin-compatible replacements may be available within the same Renesas logic portfolio; verify electrical specifications against original requirements.
