Overview
The SN74LV4066APWR is a quadruple bilateral analog switch manufactured by Texas Instruments, housed in a 14-TSSOP surface-mount package. It operates on a single supply voltage ranging from 2V to 5.5V. The device features four independent SPST-NO switches with a maximum on-resistance of 75 ohms and a channel-to-channel matching of 2 ohms. Key electrical specifications include a -3dB bandwidth of 50MHz, switch times of 12ns for both turn-on and turn-off, and an off-state leakage current of 100nA maximum. It supports an operating temperature range of -40°C to 85°C.
Feature Summary
- Provides four independent bilateral analog signal paths controlled by digital logic inputs.
- Maintains low on-resistance variation between channels for consistent signal integrity.
- Supports wide single-supply voltage operation compatible with various logic families.
Applications
- Signal routing in data acquisition systems
- Audio and video signal switching
- Programmable gain amplifier configurations
Procurement Notes
Verify the specific ordering suffix to confirm the TSSOP-14 package type and tape-and-reel packaging configuration. Ensure the component meets RoHS3 compliance requirements if mandated by your assembly process. Cross-reference the manufacturer part number with official distributor catalogs to confirm current production status and availability constraints before finalizing procurement plans.
Selection Notes
Select this component when a compact quad analog switch is required for low-voltage applications. The 14-TSSOP package offers space efficiency for dense PCB layouts. Consider the 75-ohm on-resistance limit and 50MHz bandwidth to ensure suitability for the intended signal frequency and impedance matching requirements within the circuit design.
Part Context
This part belongs to the SN74LV4066A family of quadruple bilateral analog switches. It shares core functional specifications with other variants such as the SN74LV4066ANSR (SOIC package) and SN74LV4066AN (DIP package). The primary distinction lies in the physical package geometry and mounting style, while maintaining identical electrical performance characteristics across the series.
Replacement Considerations
Direct pin-compatible alternatives include the SN74LV4066ANSR and SN74LV4066AN. Verify that the substitute package matches the board footprint and thermal requirements. Ensure the replacement maintains the same voltage range and on-resistance specifications for circuit compatibility.
