CD74HC4067EG4

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4067EG4 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 2V to 6V and features bidirectional signal paths. Key electrical parameters include a maximum on-resistance of 160 ohms, a typical break-before-make time of 6ns at 4.5V, and an operating temperature range from -55°C to +125°C. It is housed in a 24-pin PDIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific EG4 suffix against official Texas Instruments documentation to confirm lead-free status and RoHS compliance details. Ensure the PDIP-24 package dimensions match the target PCB footprint requirements. Cross-reference the manufacturer part number with authorized distributors to confirm current production status and availability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a wide supply voltage range between 2V and 6V is required for analog signal routing. The HC logic family offers lower power consumption compared to HCT variants while maintaining sufficient speed for general-purpose multiplexing. Consider the 160-ohm on-resistance limit when designing for low-voltage signal transmission to minimize attenuation errors.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the CD74HC4067 series of 16-channel analog switches. It serves as a digital-controlled analog switch within the broader 74HC logic family. The device integrates four binary select inputs to address one of sixteen channels, providing a common port for signal transmission in both directions.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The CD74HC4067E is the non-green equivalent without the G4 suffix. Other compatible parts include the CD74HC4067M (SOIC package) and CD74HC4067PW (TSSOP package). Verify pin compatibility and package dimensions before substituting.
