MUX08FP

MUX08FP Description

The MUX08FP from Analog Devices Inc. is an 8:1 analog multiplexer/demultiplexer IC designed for precision signal routing in demanding applications. Housed in a 16-pin DIP (Dual In-line Package) with through-hole mounting, this obsolete but robust component offers low leakage current (max 1nA) and moderate on-state resistance (max 300Ω), making it suitable for legacy systems requiring reliable analog switching. Its low channel capacitance (2.5pF off-state source, 7pF off-state drain) ensures minimal signal distortion, while a fast switching speed (2µs turn-on, 400ns turn-off) enhances dynamic performance.

MUX08FP Features

• Low Leakage: Max 1nA leakage current (IS(off)) preserves signal integrity in high-impedance circuits.
• Balanced On-Resistance: 300Ω max Ron with 21Ω channel-to-channel matching (ΔRon) ensures consistent signal attenuation across channels.
• Fast Switching: 2µs/400ns Ton/Toff enables rapid signal routing in time-critical applications.
• Low Capacitance: 2.5pF (CS(off)) and 7pF (CD(off)) minimize crosstalk and loading effects.
• Durable Packaging: Through-hole 16DIP in a tube package, compliant with MSL 1 (unlimited shelf life) and EAR99/8542.39.0001 export classifications.

MUX08FP Applications

• Test & Measurement Equipment: Precision multiplexing for data acquisition systems.
• Audio/Video Signal Routing: Low distortion switching in legacy AV systems.
• Industrial Control Systems: Reliable signal selection in harsh environments.
• Battery-Powered Devices: Low leakage conserves energy in portable instruments.

Conclusion of MUX08FP

While obsolete, the MUX08FP remains a viable choice for designers maintaining or upgrading older systems requiring low-noise, low-leakage analog switching. Its balanced performance in Ron, capacitance, and speed makes it ideal for precision applications where modern SMD alternatives are impractical. For new designs, consider newer Analog Devices multiplexers with enhanced specs, but the MUX08FP excels in legacy through-hole implementations.
