CD74HC4351EG4

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4351EG4 is a high-speed CMOS logic analog multiplexer manufactured by Texas Instruments. It functions as a single-pole octal-throw (SP8T) switch, providing eight independent inputs or outputs and one common input/output. The device operates with a supply voltage range of 2V to 6V for single-supply applications. It features three digital select inputs to address the channels and includes built-in address latches controlled by a latch enable input. The component is housed in a 16-pin SOIC package and is designed for low ON resistance and wide analog input voltage ranges.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates eight independent analog switches into a single SP8T configuration
• Includes digital address latches to maintain channel selection states
• Supports logic level translation between 5V logic and ±5V analog signals
• Features built-in 'break before make' switching action

Analog Switches, Multiplexers, Demultiplexers Applications

• Analog signal multiplexing and demultiplexing systems
• Digital data routing and gating circuits
• Signal processing interfaces requiring logic level translation

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status according to the manufacturer's current documentation. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range meets the environmental requirements of the target application.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an eight-channel analog switch is required within a compact surface-mount package. Consider the ON resistance specifications relative to the signal amplitude and frequency. Verify that the supply voltage range aligns with the system power rails and that the latch functionality is necessary for the design architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the Texas Instruments 74HC series of high-speed CMOS logic devices. It is functionally compatible with other industry-standard SP8T multiplexers but offers specific integration benefits from TI. The EG4 designation typically denotes a green, lead-free package variant compliant with international environmental standards.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The Nexperia 74HC4351 is a publicly confirmed substitute offering identical pinout and functional specifications. Verify compatibility regarding ESD protection levels and exact ON resistance values at the intended supply voltage before substitution.
