Overview
The MM74HC4316MX is a quad single-pole single-throw (SPST) analog switch manufactured by Fairchild Semiconductor. It operates on a single power supply ranging from 2V to 6V or dual supplies of ±1V to ±5V. The device features four independent channels with an on-resistance of 170 ohms maximum and a bandwidth of 200MHz at -3dB. It supports signal voltages up to the supply rail, offering low leakage current of 100nA maximum. Packaged in a 16-SOIC surface-mount format, it functions within a temperature range of -55°C to 125°C.
Feature Summary
- Provides four independent SPST analog switching channels for signal routing applications
- Supports true bidirectional signal transmission across the full supply voltage range
- Features low on-resistance and high bandwidth for maintaining signal integrity
Applications
- Signal multiplexing and demultiplexing in data acquisition systems
- Audio and video signal path switching
- Programmable gain amplifier input selection
Procurement Notes
Verify the manufacturer designation as Fairchild Semiconductor, noting that ON Semiconductor has integrated Fairchild's operations. Confirm the specific suffix 'MX' corresponds to the tape and reel packaging variant rather than bulk or tube formats. Ensure compatibility with the 16-SOIC footprint during component sourcing.
Selection Notes
Select this component when a quad SPST configuration is required for low-voltage analog signal routing. Consider the 170-ohm on-resistance and 200MHz bandwidth specifications against circuit requirements. Verify that the extended industrial temperature range meets environmental conditions compared to commercial grade alternatives.
Part Context
This part belongs to the 74HC series of high-speed CMOS logic devices. It serves as an analog interface solution within digital systems, allowing microcontrollers to route analog signals. The device bridges the gap between digital control logic and analog signal paths, enabling flexible system architectures.
Replacement Considerations
The CD74HC4316M96 from Texas Instruments is a recommended manufacturer substitute. The 74HC4316D,653 from Nexperia is also listed as an alternative, though availability may vary.
