MC14053BF

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14053BF is a triple 2-channel analog multiplexer/demultiplexer manufactured by onsemi in an SOEIAJ-16 package. It operates within a supply voltage range of 3.0 Vdc to 18.0 Vdc, supporting analog signal ranges up to the complete supply span. Key electrical parameters include a maximum on-resistance (Ron) of 1050 Ohms at -55°C and 300 Ohms at 125°C for a 15V supply. The device features low off-channel leakage current (±100 nA max), a bandwidth of 17 MHz, and propagation delays ranging from 9.0 ns to 65 ns depending on load capacitance and supply voltage.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Triple SPDT configuration providing three independent 2-to-1 analog switching channels
• Integrated level converter allowing direct control by standard CMOS logic levels
• Break-before-make switching action prevents momentary shorting between channels
• Triple diode protection on control inputs safeguards against high static voltages

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in data acquisition systems
• Audio signal switching and mixing applications
• Instrumentation front-end multiplexing
• Test and measurement equipment signal selection

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'F' corresponds to the SOEIAJ-16 package variant when sourcing. Confirm RoHS compliance status if environmental regulations apply to the assembly process. Ensure that the procurement documentation explicitly references the MC14053BF part number to distinguish it from other package options like BD or BCP within the same functional family.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a triple 2-channel analog switch is required with single-supply or split-supply operation. The MC14053BF is suitable for applications requiring linearized transfer characteristics and low noise. Consider the on-resistance variation over temperature and voltage when designing precision signal paths. Verify that the input signal amplitude remains within the recommended peak-to-peak limits to avoid excessive supply current draw.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MC14053B belongs to the MC1405xB series of analog multiplexers, which also includes the MC14051B (8-channel) and MC14052B (dual 4-channel). These devices share common electrical characteristics and pinout compatibility, facilitating design flexibility across different channel count requirements. The BF suffix specifically denotes the SOEIAJ-16 surface-mount package option.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MC14053BF serves as a pin-for-pin replacement for the CD4053. For applications requiring lower on-resistance, consider the HC4053 high-speed CMOS device. Other compatible alternatives within the same family include the MC14053BDG and MC14053BCPG, provided the package type matches the board layout constraints.
