MC14051BFELG

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14051BFELG is a digitally controlled analog multiplexer implementing an SP8T solid-state switch within a 16-lead SOEIAJ package. It operates on a single supply voltage ranging from 3.0 Vdc to 18 Vdc, with the analog signal range spanning the complete supply voltage difference between VDD and VEE. The device features low ON resistance, typically 280 ohms at 15 V, and very low OFF leakage current of ±100 nA. It includes triple diode protection on control inputs and provides linearized transfer characteristics with a typical noise level of 12 nV/√Hz at frequencies greater than or equal to 1.0 kHz.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Signal routing in data acquisition systems
• Multiplexing audio and video signals
• Test and measurement instrumentation front ends
• Programmable gain amplifier input selection

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix 'FELG' corresponds to the SOEIAJ-16 package type and tape-and-reel shipping configuration as defined in the manufacturer's official documentation. Confirm RoHS compliance status and lead-free material declarations match the specific batch requirements for your assembly process before finalizing orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel analog multiplexer is required with wide supply voltage flexibility up to 18 V. Ensure the application does not demand lower ON resistance values, as high-speed HC-series alternatives are recommended for such cases. Verify that the SOEIAJ-16 footprint aligns with the available PCB layout constraints and soldering capabilities.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MC1405xB family of analog multiplexers, which also includes the dual 4-channel MC14052B and triple 2-channel MC14053B. All devices share identical pinouts and functional architectures but differ in channel count and configuration. They serve as pin-for-pin replacements for legacy CD4051, CD4052, and CD4053 components.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MC14051BDR2G serves as a direct pin-compatible alternative packaged in SOIC-16. For applications requiring lower ON resistance, the HC4051 series offers high-speed CMOS performance. The MC14551B is suitable if a 4PDT switch configuration is needed instead of the SP8T topology.
