Overview
The SN74AHC4066RGYR is a quadruple bilateral analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features four independent SPST channels in a single package. The device utilizes CMOS technology for both input and output stages, ensuring low power consumption. Key electrical parameters include a maximum on-resistance of 75 Ohms and a propagation delay of 12 ns for both turn-on and turn-off times. It supports a maximum switching current of 50 mA and has a maximum supply current of 20 uA. The component is housed in a VQFN-14 package suitable for surface mount installation.
Feature Summary
- Provides four independent bilateral analog switches for signal routing applications
- Operates across a wide supply voltage range from 2 V to 5.5 V
- Features low on-resistance characteristics for efficient signal transmission
Applications
- Signal multiplexing and demultiplexing circuits
- Battery management systems for cell balancing
- Audio and video signal path switching
Procurement Notes
Verify the specific ordering suffix to confirm the tape and reel quantity matches project requirements. Confirm RoHS compliance status through official documentation before integration. Check moisture sensitivity level ratings to ensure proper handling and storage conditions are maintained during assembly processes.
Selection Notes
Select this component when multiple independent analog switches are required in a compact footprint. Ensure the operating voltage aligns with the system's power supply rails between 2 V and 5.5 V. Consider the 75 Ohm on-resistance limit for signal integrity requirements in the target application design.
Part Context
This part belongs to the SN74AHC4066 series of analog switches. It shares the same logical function as other variants but differs in packaging and shipping configuration. The RGYR suffix specifically denotes the VQFN-14 package type and reel-based delivery format used by the manufacturer.
Replacement Considerations
Direct substitutes include other SN74AHC4066 variants with compatible pinouts. Verify package dimensions and thermal characteristics when cross-referencing with alternative manufacturers' offerings.
