CD74HC4067M

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4067M is a single 16-to-1 analog multiplexer/demultiplexer manufactured by Texas Instruments. It utilizes silicon gate CMOS technology to provide high-speed switching comparable to LSTTL with standard CMOS low power consumption. The device operates on a single supply voltage ranging from 2 V to 6 V and features bidirectional signal paths. Key electrical parameters include a maximum on-resistance of 160 Ohms, a bandwidth of 89 MHz, and a propagation delay of 75 ns. It supports an operating temperature range from -55 °C to +125 °C and is housed in a 24-pin SOIC package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Bidirectional switching capability allows any analog input to function as an output and vice versa within the supply voltage range.
• Low on-resistance and low off-state leakage current ensure efficient signal transmission and isolation.
• Enable control feature disables all switches to the off state when the enable pin is held high.
• High noise immunity provides robust performance with defined noise margins relative to the supply voltage.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring multi-channel signal selection
• Process control applications involving sensor interfacing
• Audio and video signal routing in consumer electronics
• Industrial instrumentation for signal gating and modulation

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and tape/reel specifications. Ensure the ordered variant matches the required operating temperature range and logic compatibility. Cross-reference the component marking with the datasheet to validate authenticity and traceability before integration into production designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring a single 16-channel analog switch with wide voltage flexibility. The HC variant is suitable for general-purpose applications operating between 2 V and 6 V. Consider the HCT variant if direct compatibility with 5 V LSTTL logic inputs is necessary without level shifting. Evaluate thermal requirements given the extended industrial temperature range availability.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the Texas Instruments CD74HCx4067 family of high-speed CMOS analog multiplexers. The family shares identical functional characteristics but differs in packaging options and logic voltage thresholds. The M suffix typically denotes a plastic small-outline package (SOIC), distinguishing it from other form factors like SSOP or TSSOP available within the same product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

CD74HC4067SM96: Verified alternative offering identical 16:1 functionality in a 24-SSOP package. Verify pinout compatibility and package dimensions during PCB layout adaptation. Ensure voltage and current ratings remain within design limits for the substitute component.
