Overview
The NLHV4051DR2G is an 8-channel analog multiplexer/demultiplexer manufactured by onsemi in a 16-pin SOIC package. It operates within a supply voltage range of 3.0 V to 18 V and supports analog signals across the complete supply voltage span. Key electrical parameters include a maximum ON resistance of 280 Ohms at 15 V, an OFF leakage current of ±100 nA, and a bandwidth of 17 MHz. The device features a propagation delay of up to 90 ns and functions reliably across an ambient temperature range of -55°C to +125°C.
Feature Summary
- Triple diode protection integrated on control inputs for enhanced robustness
- Break-before-make switching function prevents signal overlap during channel transitions
- On-chip level converter enables direct interfacing with standard digital logic levels
Applications
- Signal routing in data acquisition systems
- Audio and video signal switching applications
- Process control instrumentation
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and check for End-of-Life notifications prior to finalizing procurement plans. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain device reliability upon installation.
Selection Notes
Select this component when high-voltage analog signal switching is required with low leakage characteristics. Verify that the operating supply voltage aligns with the 3V to 18V specification. Consider the 280 Ohm ON resistance limit for signal integrity requirements in the target application circuit design.
Part Context
This part belongs to the NLHV405x family of analog multiplexers, which also includes the NLHV4052 (Dual 4-Channel) and NLHV4053 (Triple 2-Channel). These devices share similar architectural features and pinout compatibility, allowing for flexible design scaling within the same product line.
Replacement Considerations
The datasheet identifies CD4051 as a pin-for-pin replacement reference. Designers should verify that substitute components meet the specific voltage and leakage requirements of the original design.
FAQ
What is the maximum recommended difference between VDD and VEE?
While the absolute maximum rating is 18.0 V, the datasheet recommends a maximum difference of 15 V between VDD and VEE for optimal parameter performance.
How does the device handle unused inputs?
Unused inputs must always be tied to an appropriate logic voltage level, such as VSS, VEE, or VDD, to ensure proper operation and prevent undefined states.
Is balanced power supply required for operation?
Balanced supplies are not required. However, VSS must be greater than or equal to VEE to ensure correct functionality of the internal level converters.
