Overview
The QS33X257Q1G is a high-speed quad 2-to-1 multiplexer/demultiplexer manufactured by Renesas Electronics. It operates within a supply voltage range of 4.5V to 5.5V and features low on-resistance of 15 ohms maximum. The device utilizes a 48-pin Quad Very Small Outline Package (QSOP) with a width of 3.90mm. It supports an operating temperature range from -40°C to +85°C and includes three-state outputs for bus-oriented applications. The component is classified as obsolete.
Feature Summary
- Provides four independent 2-to-1 signal paths for data routing
- Features low on-resistance for minimal signal attenuation
- Supports three-state outputs for efficient bus sharing
- Designed for hot-swap applications in high-speed digital systems
Applications
- Hot-swap controller interfaces
- High-speed data routing circuits
- Bus-oriented system architectures
Procurement Notes
This component has been officially discontinued by the manufacturer. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturing channels. Buyers must confirm the authenticity of existing stock due to the end-of-life status. Compliance documentation such as RoHS status should be verified against specific batch records, as legacy production may vary in regulatory adherence compared to current active lines.
Selection Notes
Engineers replacing this obsolete part should evaluate the QS3VH257QG8 as a potential alternative within the same manufacturer portfolio. Selection criteria must account for differences in supply voltage ranges, package dimensions, and switching characteristics between the legacy QS33X series and newer variants. Compatibility checks are required to ensure pinout alignment and electrical parameter matching for the target application environment.
Part Context
The QS33X257Q1G belongs to the QS33X257 family of logic ICs produced by Renesas Electronics. This series was designed for high-performance multiplexing tasks in digital electronics. The specific Q1G suffix denotes the lead-free and halogen-free compliant version packaged in the 48-QSOP format. It falls under the broader category of encoders, decoders, and multiplexers used in interface circuitry.
Replacement Considerations
The QS3VH257QG8 is identified as a related product in the manufacturer's lineup. Verify voltage compatibility and package footprint before substitution.
