NLAS4051DTR2G Description

The NLAS4051DTR2G from onsemi is an 8:1 single-channel analog multiplexer/demultiplexer IC designed for precision signal routing in low-voltage applications. Housed in a compact 16-pin TSSOP package and delivered in tape & reel (TR) format, this obsolete but still relevant component offers robust performance with an on-state resistance (Ron) of just 26Ω (max) and excellent channel-to-channel matching (ΔRon = 10Ω). It operates over a wide single-supply voltage range (2.5V to 5V) or dual-supply (±3V), making it versatile for mixed-signal systems. With a -3dB bandwidth of 95MHz and fast switching times (23ns Ton/Toff), it ensures minimal signal distortion in high-speed applications.

NLAS4051DTR2G Features

• Low Leakage Current: Max 100nA (IS(off)) ensures minimal power loss in standby.
• High-Speed Switching: 23ns transition time for rapid signal routing.
• Low Charge Injection: 12pC reduces glitch effects in sensitive circuits.
• Low Capacitance: 10pF (CS(off)/CD(off)) minimizes crosstalk and signal degradation.
• Wide Voltage Range: Supports 2.5V–5V (single) or ±3V (dual) supplies.
• 95MHz Bandwidth: Ideal for high-frequency analog/digital signals.
• ROHS3 Compliant & REACH Unaffected: Meets environmental standards.

NLAS4051DTR2G Applications

This multiplexer excels in precision applications requiring low distortion and high signal integrity:

• Test & Measurement Equipment: Signal routing in oscilloscopes or data acquisition systems.
• Audio/Video Switching: Low-noise signal multiplexing in portable devices.
• Battery-Powered Systems: Energy-efficient operation extends battery life.
• Industrial Automation: Reliable performance in sensor arrays and control systems.
• Communication Systems: High-bandwidth signal handling in RF/IF stages.

Conclusion of NLAS4051DTR2G

The NLAS4051DTR2G combines low Ron, fast switching, and wide voltage compatibility, making it a strong choice for legacy designs or replacements in signal-path applications. While marked obsolete, its 95MHz bandwidth, low charge injection, and 10pF channel capacitance ensure competitive performance in high-speed, low-power systems. Engineers valuing signal fidelity and compact packaging will find it suitable for audio, instrumentation, and portable electronics.
