M74HCT4051ADTR2G Description

The M74HCT4051ADTR2G from onsemi is a high-performance 8:1 analog multiplexer/demultiplexer IC designed for precision signal routing in mixed-signal applications. Packaged in a 16-pin TSSOP and delivered in Tape & Reel (TR), 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 handling. With an on-state resistance (Ron) of just 100Ω (max) and tight channel-to-channel matching (ΔRon = 10Ω), it ensures minimal signal distortion and high accuracy. Its low leakage current (200nA max) and 80MHz bandwidth further enhance signal integrity, while the 130pF channel capacitance minimizes crosstalk.

M74HCT4051ADTR2G Features

• Low Power Consumption: Compatible with HCT logic levels, reducing power dissipation.
• Wide Voltage Range: Supports ±2V to ±6V dual supply or 2V–6V single supply, ideal for mixed-voltage systems.
• High Signal Fidelity: 80MHz bandwidth and low Ron (100Ω max) ensure minimal attenuation for high-frequency signals.
• Low Crosstalk: 130pF off-channel capacitance reduces interference between signals.
• Robust Design: ROHS3 compliant and REACH unaffected, meeting stringent environmental standards.
• Surface-Mount Ready: MSL 1 (Unlimited) rating allows for extended storage without moisture sensitivity concerns.
