CD74HC4351M96

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4351M96 is a high-speed CMOS analog multiplexer manufactured by Texas Instruments, belonging to the CD74HC4000 series. It integrates a single 8-channel multiplexer with three binary select inputs and one active-low enable input, housed in a surface-mount SOIC-16 package. The device operates on a single supply voltage ranging from 2 V to 6 V. Key electrical specifications include a maximum propagation delay of 35 ns at 5 V, an off-isolation of -50 dB, and a bandwidth of 250 MHz. It supports an extended industrial operating temperature range from -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates eight independent analog channels into a single compact package for efficient signal routing.
• Features low on-resistance (typically 60 ohms) and excellent channel-to-channel matching for accurate signal transmission.
• Includes an active-low enable pin that allows easy cascading or system-level power management control.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring multi-channel signal selection.
• Programmable gain amplifier circuits.
• Audio signal routing and switching applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'M96' against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure the ordering part number matches the required RoHS compliance status and moisture sensitivity level for your assembly process. Cross-reference the distributor's component description with official TI documentation to avoid confusion with similar logic families.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel analog switch is required within the HC logic family voltage range. Compare the 250 MHz bandwidth and 35 ns propagation delay against system timing requirements. Consider the SOIC-16 thermal performance if multiple units are placed closely on the PCB. Verify that the input signal levels remain within the absolute maximum ratings relative to the chosen supply voltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part is part of the Texas Instruments CD74HC4000 series of high-speed CMOS logic devices. The CD74HC4351 specifically addresses analog switching needs, differing from digital logic gates or standard digital multiplexers by its ability to pass analog signals with low distortion. It complements other series components like the CD74HC4051 (16-channel) or CD74HC4052 (dual 4-channel) for scalable design architectures.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional equivalents include the CD74HC4051 for expanded channel count or CD74HC4052 for dual 4-channel configurations. Check for pin-compatible alternatives such as the SN74HC4351 if lead-free processing requirements differ. Verify that substitute parts maintain the same 2V-6V operating voltage and SOIC-16 footprint constraints.
