MC14052BFELG Description

The MC14052BFELG from onsemi is a dual 4-channel analog multiplexer/demultiplexer (2:4 configuration) designed for precision signal routing in low-voltage applications. Housed in a 16-pin SOEIAJ package, this surface-mount IC features a maximum on-state resistance (Ron) of 280Ω and operates across a wide supply voltage range of 3V to 18V, making it versatile for mixed-voltage systems. With a -3dB bandwidth of 17MHz, it supports moderate-frequency analog and digital signals while maintaining low distortion. The device exhibits low leakage current (100nA max) and minimal channel-to-channel mismatch (ΔRon of 10Ω), ensuring consistent performance in multiplexing applications.

MC14052BFELG Features

• Low On-Resistance: 280Ω max ensures minimal signal attenuation.
• Wide Voltage Range: 3V to 18V single-supply operation for compatibility with TTL, CMOS, and industrial logic levels.
• High Bandwidth: 17MHz -3dB bandwidth suitable for audio, video, and data switching.
• Low Leakage: 100nA max (IS(off)) reduces power loss in standby modes.
• Matched Channels: ΔRon of 10Ω enhances signal integrity in differential applications.
• Compact Packaging: 16-pin SOEIAJ (Tape & Reel) for automated assembly.
• Low Capacitance: 7.5pF channel capacitance (CS(off)/CD(off)) minimizes crosstalk.

MC14052BFELG Applications

• Signal Routing: Ideal for audio/video switching, data acquisition systems, and test equipment due to low distortion.
• Battery-Powered Devices: Low leakage current suits portable electronics and IoT sensors.
• Industrial Control: Robust performance in PLC modules, instrumentation, and automation systems.
• Telecom Systems: Channel multiplexing in low-frequency communication circuits.
• Legacy Upgrades: Replaces obsolete mechanical relays in retrofit designs.

Conclusion of MC14052BFELG

The MC14052BFELG excels in low-voltage, precision signal routing with its balanced trade-off between Ron, bandwidth, and power efficiency. While marked obsolete, its REACH compliance and industry-standard footprint make it a reliable choice for legacy designs or inventory-based projects. Engineers valuing low crosstalk, matched channels, and broad voltage support will find it particularly useful in mixed-signal systems where signal fidelity is critical. For new designs, consider onsemi’s active alternatives with enhanced specs.
