Overview
The MM74HC4316WMX is a high-speed CMOS quad analog switch manufactured by Fairchild Semiconductor. It features four independent SPST switches in a 16-pin SOIC package. The device operates on a single supply voltage ranging from 2V to 6V, with a maximum on-resistance of 70 ohms and low off-isolation capacitance. It supports bidirectional signal transmission with low distortion, making it suitable for precision analog applications requiring fast switching speeds and low power consumption.
Feature Summary
- Quad configuration providing four independent single-pole single-throw (SPST) analog switches within a single integrated circuit.
- High-speed CMOS technology enabling rapid switching transitions with minimal propagation delay for efficient signal routing.
- Low on-resistance characteristic ensures minimal signal attenuation and voltage drop across the conductive path during the active state.
Applications
- Signal multiplexing and demultiplexing in data acquisition systems
- Audio and video signal routing in consumer electronics
- Programmable gain amplifiers and sensor interface circuits
Procurement Notes
Verify the manufacturer designation carefully, as Fairchild Semiconductor's logic division was acquired by ON Semiconductor. Confirm that the specific part number corresponds to the original Fairchild production run or its direct successor lineage to ensure compatibility with existing design specifications and quality standards.
Selection Notes
Select this component when a compact solution for multiple analog signal paths is required. Ensure the operating voltage range aligns with the system's power supply constraints. Verify that the package type matches the PCB footprint requirements and that the thermal characteristics are sufficient for the intended application environment.
Part Context
This component belongs to the standard 74HC series of logic devices, widely recognized for their compatibility with various digital control interfaces. The 4316 variant specifically addresses analog switching needs, bridging the gap between pure digital logic and discrete analog components in mixed-signal designs.
Replacement Considerations
Check for equivalents such as the CD74HC4316 from Texas Instruments or the M74HC4316 from STMicroelectronics. These parts share similar pinouts and electrical characteristics but may differ in specific parameter tolerances or packaging options.
