Overview
The SN74LV4066APWT is a quadruple bilateral analog switch manufactured by Texas Instruments. It features four independent single-pole single-throw (SPST) switches within a 14-TSSOP package. The device operates on a single supply voltage ranging from 2V to 5.5V. Key electrical parameters include a maximum on-resistance of 75 ohms and a channel-to-channel matching of 2 ohms. Switching times are specified at a maximum of 12ns for both turn-on and turn-off. The component supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Provides four independent bilateral analog signal paths for flexible circuit routing
- Supports low-voltage digital logic interfaces with wide power supply compatibility
- Ensures signal integrity through low on-resistance and high off-isolation characteristics
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal path switching
- Battery-powered portable equipment requiring low standby current
Procurement Notes
Verify the specific suffix 'PWT' against the manufacturer's official documentation to confirm the exact tape-and-reel quantity and moisture sensitivity level. Ensure the ordering information matches the required packaging format for automated assembly processes. Cross-reference the RoHS compliance status with the latest product data sheet revision history.
Selection Notes
Select this component when designing circuits that require multiple independent analog switches in a compact surface-mount footprint. Consider the 75-ohm on-resistance limit for applications involving higher signal currents or strict voltage drop requirements. Evaluate the 2V minimum supply voltage constraint to ensure compatibility with the system's power rail architecture.
Part Context
This part belongs to the SN74LV4066A family of quadruple analog switches. It shares functional similarities with other members of the LV series but differs in packaging and specific suffix designations. The TSSOP-14 package allows for space-constrained PCB layouts compared to larger DIP alternatives.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify pinout compatibility and electrical specifications before considering any alternative components from different manufacturers.
