MM74HC4316M

Overview

The MM74HC4316M is a high-speed CMOS analog switch manufactured by Fairchild Semiconductor, part of the 74HC series. It integrates four independent single-pole single-throw (SPST) normally-open switches within a 16-pin SOIC package. The device operates on a single supply voltage ranging from 2V to 6V or dual supplies of ±1V to ±5V. Key electrical characteristics include a maximum on-resistance of 170 ohms, a channel-to-channel matching of 5 ohms, and a -3dB bandwidth of 200MHz. Switching times are specified at a maximum of 37ns for both turn-on and turn-off. The component supports an operating temperature range from -55°C to 125°C.

Feature Summary

• Integrates four independent SPST analog switches in a compact surface-mount package
• High-speed switching performance with 200MHz bandwidth and 37ns transition times
• Wide operating voltage compatibility supporting both single and dual supply configurations
• Robust thermal stability suitable for extended industrial temperature environments

Applications

• Signal routing in data acquisition systems
• Audio signal path switching
• Instrumentation input multiplexing

Procurement Notes

Verify the manufacturer status as Fairchild Semiconductor has undergone corporate restructuring and its semiconductor assets were acquired by ON Semiconductor. Confirm that the specific MM74HC4316M part number remains available from authorized distributors or check for equivalent current production parts from the successor entity to ensure supply chain continuity.

Selection Notes

Select this component when four isolated analog channels are required in a small footprint. Ensure the application voltage stays within the 2V to 6V single-supply limit to maintain the specified 170-ohm on-resistance. Verify that the 37ns switching speed meets the system timing requirements and that the 16-SOIC package dimensions fit the PCB layout constraints.

Part Context

This component belongs to the standard 74HC logic family, known for CMOS compatibility and low power consumption. It serves as a general-purpose analog switch solution for commercial and industrial electronics. The device provides a cost-effective alternative to discrete transistor-based switching networks while offering predictable on-resistance and leakage characteristics.

Replacement Considerations

Check for equivalents such as the CD74HC4316M from Texas Instruments, which shares identical pinout and functional specifications. Verify package compatibility and electrical parameter tolerances before substituting.
