MC74HC4051ADG

MC74HC4051ADG Description

The MC74HC4051ADG from onsemi is a high-performance 8:1 analog multiplexer/demultiplexer IC designed for precision signal routing in mixed-signal systems. Housed in a 16-SOIC package, this device operates with a single supply voltage (2V–6V) or dual supply (±2V–6V), making it versatile for both single-ended and differential signal applications. With an on-state resistance (Ron) of just 100Ω (max) and low channel-to-channel matching (ΔRon = 10Ω), it ensures minimal signal distortion and high accuracy. The 80MHz bandwidth and low off-state leakage (200nA max) further enhance its suitability for high-speed, low-power designs.

MC74HC4051ADG Features

• Low Power Consumption: Optimized for battery-operated devices with minimal leakage current.
• Wide Voltage Range: Supports 2V–6V (single) or ±2V–6V (dual) supplies, enabling compatibility with TTL and CMOS logic levels.
• High Signal Integrity: 100Ω max on-resistance and 10Ω channel matching reduce signal attenuation and crosstalk.
• Fast Switching: 80MHz bandwidth ensures reliable performance in high-frequency applications.
• Robust Packaging: 16-SOIC surface-mount package (MSL 1) offers reliability for automated assembly.
• Low Capacitance: 130pF channel capacitance (CS/CD off) minimizes loading effects.
• Compliance: ROHS3 and REACH compliant, meeting environmental standards.

MC74HC4051ADG Applications

• Data Acquisition Systems: Ideal for multiplexing analog sensor signals in industrial or medical equipment.
