Overview
The QS4A210QG is a dual single-pole four-throw (SP4T) analog switch manufactured by Renesas Electronics Corporation. It features two independent 4:1 multiplexer circuits housed in a 16-lead Quad Small Outline Package (QSOP). The device operates with a single 5V supply and offers a maximum on-resistance of 17 ohms. 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 supports an operating temperature range from -40°C to 85°C and is RoHS3 compliant.
Feature Summary
- Dual SP4T configuration providing two independent 4:1 signal routing paths within a single package
- High-speed performance characterized by a 700MHz -3dB bandwidth and 6ns switching transitions
- Low distortion attributes including minimal charge injection and low off-state leakage current
Applications
- Signal routing in communication systems requiring high-frequency isolation
- Test and measurement equipment utilizing multi-channel data acquisition
- Video distribution networks managing multiple input sources
Procurement Notes
Verify the manufacturer status as the QS4A210QG is listed as obsolete or end-of-life. Confirm availability through authorized distributors or secondary market suppliers. Check for specific ordering suffixes that may indicate packaging variations or material changes. Ensure compliance with current environmental regulations such as RoHS3 before procurement.
Selection Notes
Select this component when dual independent 4:1 switching is required in a compact surface-mount footprint. Consider the 17-ohm on-resistance and 700MHz bandwidth limits for signal integrity requirements. Evaluate the 16-QSOP package dimensions against board space constraints. Verify power supply compatibility with the specified 5V single-supply operation.
Part Context
The QS4A210QG belongs to the QS4A210 family of analog switches. It was originally developed by Integrated Device Technology (IDT), which was later acquired by Renesas Electronics. The part serves as a specialized interface solution for managing multiple signal lines in electronic systems requiring fast and reliable switching capabilities.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements should be verified against pinout compatibility and electrical specifications with equivalent manufacturers.
