CD74HCT4051M Description

The CD74HCT4051M from Texas Instruments is a high-performance 8:1 analog multiplexer/demultiplexer designed for precision signal routing in mixed-signal systems. Housed in a 16-SOIC package, this IC features a low on-state resistance (130Ω max) and minimal channel-to-channel matching (ΔRon = 5Ω), ensuring consistent signal integrity across all channels. It operates over a dual supply range of ±1V to 5V or a single supply of 4.5V to 5.5V, making it versatile for both bipolar and unipolar applications. With an impressive -3dB bandwidth of 180MHz and low leakage current (400nA max), it excels in high-speed, low-power designs.

CD74HCT4051M Features

• Low Power Consumption: Leakage current as low as 400nA (IS(off)) minimizes power dissipation.
• High-Speed Performance: 180MHz bandwidth supports fast signal switching.
• Low On-Resistance: 130Ω max (Ron) reduces signal attenuation.
• Excellent Channel Matching: ΔRon of 5Ω ensures uniform performance.
• Wide Voltage Range: Compatible with ±1V to 5V (dual) or 4.5V–5.5V (single) supplies.
• Low Capacitance: 5pF (CS(off)) and 25pF (CD(off)) minimize crosstalk.
• Robust Packaging: 16-SOIC with MSL 1 (Unlimited) moisture sensitivity for reliability.
• Compliance: ROHS3 and REACH Unaffected, meeting environmental standards.

CD74HCT4051M Applications

• Data Acquisition Systems: Ideal for multiplexing analog sensor signals with minimal distortion.
• Audio/Video Switching: Low capacitance and high bandwidth ensure clean signal routing.
• Test & Measurement Equipment: Precision channel matching supports accurate signal conditioning.
• Battery-Powered Devices: Ultra-low leakage current extends battery life.
• Industrial Control Systems: Wide voltage range accommodates diverse logic levels.

Conclusion of CD74HCT4051M

The CD74HCT4051M stands out for its low on-resistance, high bandwidth, and superior channel matching, making it a top choice for high-speed, low-power multiplexing. Its dual/single supply flexibility and robust packaging cater to demanding applications in industrial, automotive, and consumer electronics. While marked as Last Time Buy, its performance metrics ensure it remains a reliable solution for legacy and new designs requiring precision analog switching.
