MC14051BF

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14051BF is a digitally controlled analog switch implementing an SP8T solid-state switch within the MC14051B series. It operates on a single supply voltage ranging from 3.0 Vdc to 18 Vdc, with an analog signal range spanning the complete supply voltage span. The device features low ON impedance and very low OFF leakage current, ensuring efficient signal routing. It includes triple diode protection on control inputs and utilizes a break-before-make switching function. The component supports linearized transfer characteristics and low noise performance, operating reliably across a temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package suffix 'F' corresponds to the SOEIAJ-16 form factor when sourcing. Confirm RoHS compliance status as standard versions may differ from lead-free designations. Ensure the ordering code matches the exact manufacturer part number to avoid functional discrepancies in pinout or electrical specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring a single 8-channel analog multiplexer with wide supply voltage flexibility. Consider the HC4051 variant if lower ON resistance is required for high-speed applications. Verify that the control logic levels align with the VDD and VSS supply rails defined in the system architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MC1405xB family of analog multiplexers, which also includes the dual 4-channel MC14052B and triple 2-channel MC14053B. All three devices share similar electrical characteristics and pin compatibility, allowing for flexible design scaling based on channel count requirements while maintaining consistent interface standards.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet specifies pin-for-pin replacement for CD4051 devices. Designers should verify that substitute components maintain equivalent ON resistance and leakage current specifications to ensure signal integrity is preserved in the application circuit.
