MC14053BFEL

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14053BFEL is a triple 2-channel analog multiplexer/demultiplexer manufactured by onsemi in the SOEIAJ-16 package. It features low ON impedance and very low OFF leakage current, enabling control of analog signals across the complete supply voltage range. The device operates with a DC supply voltage range of 3.0 Vdc to 18.0 Vdc and an analog voltage range of 3.0 V to 18 V. Key electrical parameters include a maximum ON resistance of 280 Ω at 15 V supply, off-channel leakage current of ±100 nA, and a bandwidth of 17 MHz. It provides pin-for-pin replacement for CD4053 devices.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Triple SPDT switch configuration with digitally controlled analog switching

• Built-in level converter allowing direct interface with standard CMOS logic
• Break-before-make switching function prevents signal shorting

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in data acquisition systems
• Audio signal switching and mixing applications
• Test and measurement equipment signal paths
• Industrial process control signal multiplexing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix BFEL corresponds to the SOEIAJ-16 tape and reel packaging containing 2000 units per reel. Confirm RoHS compliance status if required, as non-compliant variants exist within the same family. Ensure the specific revision of the datasheet matches the production batch for accurate parameter validation during component qualification.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a triple 2-channel analog switch is required with low distortion and wide dynamic range. The MC14053B offers superior linearity compared to basic switches. Consider the HC4053 variant if lower ON resistance is critical, or the MC14551B if a 4PDT configuration is needed instead of three separate SPDT channels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MC1405xB series of analog multiplexers, which also includes the MC14051B (8-channel) and MC14052B (dual 4-channel). These devices share common architectural features such as the internal level converter and protection circuitry. The series is designed for general-purpose analog signal switching in industrial and consumer electronics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MC14053BCP, MC14053BD, and MC14053BDTR2G are functional equivalents offering different packaging options such as PDIP-16, SOIC-16, and TSSOP-16 respectively. Verify pin compatibility and thermal characteristics when substituting packages.
