Overview
The SN74HC4066NSR is a quadruple bilateral analog switch manufactured by Texas Instruments, belonging to the 74HC series of high-speed CMOS logic devices. It features four independent SPST switches in a 14-pin SOIC package. The device operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40 °C to +85 °C. Key electrical characteristics include a maximum on-resistance of 70 ohms at 5 V, a typical turn-on/turn-off time of 10 ns/30 ns, and a leakage current of 20 nA. It is designed for applications requiring low power consumption and compatibility with LSTTL loads.
Feature Summary
- Provides four independent single-pole single-throw (SPST) analog signal paths for bidirectional switching
- CMOS technology ensures low static power consumption while maintaining speed comparable to LSTTL logic families
- Operates across a wide supply voltage range suitable for various digital system interfaces
Applications
- Signal routing in data acquisition systems
- Audio and video signal switching
- Multiplexing applications in communication equipment
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives as indicated in the component datasheet. Confirm moisture sensitivity level requirements for surface-mount assembly processes prior to procurement.
Selection Notes
Select this component when a quadruple analog switch with HC-series speed and voltage compatibility is required. Compare on-resistance values and leakage currents against application requirements. Consider alternative packages such as TSSOP or PDIP if pin configuration constraints differ from the standard SOIC-14 footprint.
Part Context
This part belongs to the Texas Instruments 74HC4066 family of analog switches. The 'N' suffix typically denotes the SOIC package variant, while 'SR' indicates reel packaging. It serves as a functional equivalent to other manufacturers' 74HC4066 parts, providing industry-standard pinouts for easy replacement in existing designs.
Replacement Considerations
Cross-reference with CD74HC4066M or MM74HC4066SJ for pin-compatible alternatives. Verify that substitute components meet the same 70-ohm on-resistance and 2V-6V operating voltage specifications.
