Overview
The SN74LV4066ARGYRG4 is a quadruple bilateral analog switch manufactured by Texas Instruments, belonging to the LV (Low Voltage CMOS) logic family. It integrates four independent single-pole single-throw (SPST) switches in a compact VQFN package. The device operates on a single power supply ranging from 2V to 5.5V, ensuring compatibility with modern low-voltage digital systems. Key electrical characteristics include a maximum on-resistance of 75 ohms and a channel-to-channel matching of 2 ohms, which supports precise signal routing. The component features a -3dB bandwidth of 50MHz and offers low off-state leakage current, making it suitable for applications requiring efficient analog signal switching within constrained space and power budgets.
Feature Summary
- Integrates four independent bilateral analog switches for flexible signal routing
- Operates across a wide single-supply voltage range from 2V to 5.5V
- Provides low on-resistance with tight channel-to-channel matching for signal integrity
- Features high bandwidth and low off-state leakage for effective isolation
Applications
- Battery-powered portable equipment requiring low voltage operation
- Signal multiplexing and demultiplexing in data acquisition systems
- Audio and video signal path switching in consumer electronics
- Sample-and-hold circuits in analog-to-digital converter interfaces
Procurement Notes
Verify the specific suffix 'RGYR' corresponds to the VQFN-14 package and tape-and-reel quantity when sourcing. Confirm RoHS compliance status as indicated by the 'G4' suffix. Ensure the supplier provides traceability documentation consistent with Texas Instruments manufacturing standards. Cross-reference the DigiKey or Mouser part numbers to validate packaging details before finalizing procurement orders.
Selection Notes
Select this component when a quad SPST analog switch is required in a small form factor. The LV series is appropriate for systems operating between 2V and 5.5V. Compare on-resistance specifications against load requirements to ensure minimal signal attenuation. Consider the thermal performance of the VQFN package if multiple switches are activated simultaneously under heavy load conditions.
Part Context
This part is a variant of the SN74LV4066A family, distinguished by its VQFN-14 package (suffix RGYR) and lead-free/plane termination (suffix G4). It shares the same internal circuitry and electrical specifications as other SN74LV4066 variants but differs in physical footprint and mounting style. The LV technology ensures low power consumption while maintaining speed comparable to standard CMOS devices.
Replacement Considerations
Direct pin-compatible replacements include SN74LV4066APWR (TSSOP-14) and SN74LV4066ANSR (SOIC-14), though package dimensions differ. For identical VQFN-14 packages, verify availability of SN74LV4066RGYT or similar TI variants. Ensure substitute parts meet the 2V minimum supply voltage requirement.
