NLAS4051DTR2G

Overview

The NLAS4051DTR2G is an onsemi analog multiplexer/demultiplexer IC belonging to the NLAS4051 series. It features a single 8:1 circuit configuration housed in a 16-TSSOP surface-mount package. The device operates within a supply voltage range of 2.5V to 5V for single-supply applications. Key electrical specifications include a maximum on-resistance of 26 ohms, a -3dB bandwidth of 95MHz, and a channel-to-channel matching (ΔRon) of 10 ohms. Switching performance is characterized by a maximum turn-on time of 23ns and a maximum turn-off time of 23ns. The component supports a wide operating temperature range from -55°C to +125°C.

Feature Summary

• High-speed signal switching with 95MHz bandwidth and 23ns transition times
• Low on-resistance of 26 ohms ensuring minimal signal attenuation
• Tight channel-to-channel matching for consistent multi-channel performance
• Wide operating temperature range suitable for industrial environments

Applications

• Portable battery-powered equipment requiring low-voltage operation
• Industrial process control systems needing wide temperature tolerance
• Automotive electronics applications certified under AEC-Q101 standards

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with onsemi or authorized distributors before procurement. Confirm that the 16-TSSOP package dimensions align with your PCB footprint requirements. Ensure that the 2.5V to 5V supply voltage range meets your system design constraints. Check for any recent Product Change Notifications (PCN) regarding manufacturing location or material changes. Validate that the component's leakage current and capacitance parameters are acceptable for your specific signal integrity needs.

Selection Notes

Select this component when a low-voltage, high-speed analog switch is required for 8:1 multiplexing tasks. The NLAS4051DTR2G is suitable for designs prioritizing low power consumption and fast switching speeds over high voltage handling capabilities. Compare its 26-ohm on-resistance against other series members if lower resistance is critical for your application. Consider the 16-TSSOP package size relative to available board space. Evaluate the -55°C to +125°C operating range against your environmental conditions.

Part Context

This part belongs to the NLAS4051 family of low-voltage analog switches. It shares functional similarities with other 74-series logic multiplexers but is optimized for lower voltage operations. The NLAS series typically offers improved speed and power efficiency compared to older HC or HCT counterparts. It serves as a direct replacement for legacy components in modern low-power designs requiring reliable analog signal routing.

Replacement Considerations

Direct substitutes may include other onsemi NLAS4051 variants with different packaging options. Cross-reference with similar 8:1 analog switches from other manufacturers if supply constraints exist. Verify pin compatibility and electrical parameter equivalence before substituting.
