MC14053BFG

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14053BFG is a Triple SPDT Analog Multiplexer/Demultiplexer manufactured by onsemi. It operates within a supply voltage range of 3.0 Vdc to 18.0 Vdc and supports analog signal ranges from 3.0 V to 18.0 V. The device features low ON impedance, very low OFF leakage current, and linearized transfer characteristics. It includes triple diode protection on control inputs and utilizes a break-before-make switching function. The component is housed in an SOEIAJ-16 surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Multiplexing multiple sensor inputs into a single ADC channel
• Analog signal switching in test and measurement equipment

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'F' corresponds to the SOEIAJ-16 package type as defined in the manufacturer's ordering information. Confirm RoHS compliance status for the specific batch, noting that 'G' or similar suffixes typically indicate lead-free packaging while standard suffixes may vary. Ensure the component matches the exact pinout and electrical specifications required for the target circuit design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a triple single-pole double-throw analog switch is required within a 3V to 18V operating range. Consider the MC14053B series for applications needing low off-state leakage and high channel isolation. Evaluate the SOEIAJ-16 package dimensions against available PCB real estate constraints compared to alternative packages like SOIC-16 or TSSOP-16.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MC14053B belongs to the MC1405xB family of analog multiplexers, which also includes the MC14051B (SP8T) and MC14052B (DP4T). These devices share common architectural features such as CMOS technology and integrated level converters. The MC14053B specifically provides three independent switches, making it suitable for applications requiring simultaneous selection among three distinct signal paths.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet identifies CD4053 as a pin-for-pin replacement candidate. For lower ON resistance requirements, HC4053 devices are suggested. Verify compatibility regarding package dimensions and electrical parameters before substituting.
