Overview
The QS4A210XQ is a dual single-pole quadruple-throw (SP4T) analog switch manufactured by Renesas Electronics Corporation, formerly IDT. It integrates two independent 4:1 multiplexer circuits within a single 16-pin Quad Small Outline Package (QSOP). The device features a maximum on-resistance of 17 ohms and supports a single 5V power supply. Key electrical specifications include a -3dB bandwidth of 700MHz, charge injection of 1.5pC, and leakage current of 2nA. Switching times are rated at 6ns for both turn-on and turn-off. The component operates within a temperature range of -40°C to 85°C.
Feature Summary
- Dual SP4T configuration providing two independent signal routing paths.
Applications
- Signal routing in communication systems
Procurement Notes
Verify the manufacturer status as Renesas Electronics Corporation, noting the historical IDT branding. Confirm the specific suffix 'XQ' against official datasheets to ensure package and material compliance. Check for End-of-Life notifications or Product Change Notices affecting availability. Validate RoHS3 compliance and moisture sensitivity level requirements for assembly processes.
Selection Notes
Select this component when dual independent 4-to-1 switching is required with low distortion characteristics. Ensure the 17-ohm on-resistance meets system loss budgets. Verify that the 16-QSOP package dimensions fit the PCB layout constraints. Confirm compatibility with the 5V single-supply operation and required signal bandwidth up to 700MHz.
Part Context
This part belongs to the QS4A210 family of high-speed analog switches. The base model QS4A210 defines the core electrical performance. Suffixes typically indicate package variations or environmental ratings. The transition from IDT to Renesas affects documentation sources but maintains technical continuity for existing designs.
Replacement Considerations
Consult official substitution guides for equivalent dual SP4T switches. Verify pinout compatibility and on-resistance matching before replacing. Consider packages such as 16-SSOP if physical footprint adjustments are permissible. Ensure thermal and electrical parameters align with original design specifications.
