NLVHC4051ADWR2

Overview

The NLVHC4051ADWR2 is a single analog multiplexer/demultiplexer manufactured by onsemi. It features eight independent channels and utilizes CMOS technology for low power consumption. The device operates with a supply voltage range of 2.0 V to 5.5 V. Key electrical parameters include a maximum on-resistance of 35 ohms at 5 V and propagation delays typically around 8 ns. It supports logic level translation, allowing 5 V digital signals to interface with analog signals ranging from -5 V to +5 V. The component is housed in an 8-pin SOIC package.

Feature Summary

• Provides eight independent analog signal paths for routing applications
• Enables direct interfacing between 5 V logic systems and wider analog voltage ranges
• Utilizes advanced CMOS process technology to minimize static and dynamic power dissipation

Applications

• Data acquisition systems requiring multi-channel signal selection
• Audio signal routing and switching circuits
• Industrial control systems for sensor input multiplexing

Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and check for automotive qualification status if required for the target application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current production status and availability constraints.

Selection Notes

Select this component when designing circuits that require multiple analog inputs to be routed to a single output under microcontroller control. Consider the on-resistance variation across the voltage range and temperature spectrum. Evaluate the need for channel isolation and crosstalk performance relative to the signal frequency. Confirm that the operating supply voltage aligns with the system's logic levels and analog signal swings.

Part Context

This part belongs to the NLVHC series of high-speed CMOS logic devices from onsemi. The series focuses on low-voltage operation and compatibility with standard 5 V logic families. It serves as a modern replacement for older bipolar or NMOS multiplexer technologies, offering improved speed and lower power consumption while maintaining pin-out compatibility with legacy designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the HC or HCT logic families from other manufacturers. Verify that substitute parts meet the same analog switch specifications regarding on-resistance and breakdown voltage. Ensure that any replacement maintains the same package dimensions and thermal characteristics for existing PCB layouts.
