Overview
The MM74HC4316WM is a high-speed CMOS analog switch manufactured by Fairchild Semiconductor, housed in a 16-pin SOIC surface-mount package. It integrates four independent single-pole double-throw (SPDT) switches designed for low on-resistance and minimal signal distortion. The device operates within a supply voltage range of 2V to 12V for single supplies or ±1V to ±6V for dual supplies. Key electrical characteristics include a maximum on-resistance of 70 ohms, a channel-to-channel matching of 5 ohms, and an off-leakage current of 100nA. It supports a -3dB bandwidth of 43MHz with switching times of 18ns (Ton) and 29ns (Toff). The component functions reliably across an extended temperature range from -55°C to +125°C.
Feature Summary
- Integrates four independent SPDT analog switches in a compact 16-SOIC package
- Provides low on-resistance and tight channel-to-channel matching for signal integrity
- Operates over a wide dual-supply voltage range of ±1V to ±6V
- Features low off-state leakage current and high bandwidth performance
Applications
- Signal routing in data acquisition systems
- Audio and video signal switching applications
- Programmable gain amplifier circuits
- Multiplexing sensor inputs in industrial control
Procurement Notes
Verify the manufacturer origin carefully as Fairchild Semiconductor's logic division was acquired by ON Semiconductor. Confirm the specific suffix 'WM' corresponds to the SOIC package variant. Check for RoHS compliance status and moisture sensitivity level requirements during storage and handling. Ensure the part number matches the exact pinout and electrical specifications required for the design.
Selection Notes
Select this component when multiple independent SPDT switching paths are required in a small footprint. Consider the 70-ohm on-resistance limit for signal loss calculations. Verify that the operating voltage range aligns with the system's power rails. Compare the 43MHz bandwidth against the highest frequency signal to be switched to ensure minimal attenuation.
Part Context
This part belongs to the 74HC series of high-speed CMOS logic devices, known for compatibility with standard TTL logic levels while offering improved speed and lower power consumption compared to older HC variants. The 4316 designation specifically identifies the quad SPDT analog switch configuration within this family.
Replacement Considerations
The M74HC4316RM13TR from STMicroelectronics is a documented alternative. The 74HC4316D,653 from Nexperia is also listed as a similar replacement option.
