Analog Switches, Multiplexers, Demultiplexers datasheet and documents for MC14051BFG
Analog Switches, Multiplexers, Demultiplexers Overview
The MC14051BFG is a digitally controlled analog switch implementing an SP8T solid-state switch within the MC14051B series. It features low ON impedance and very low OFF leakage current, allowing control of analog signals across the complete supply voltage range. The device operates with a supply voltage range of 3.0 Vdc to 18 Vdc and supports an analog voltage range (VDD − VEE) of 3.0 to 18 V. Key electrical parameters include a maximum ON resistance of 1200 Ω at 5.0 V supply and typical propagation delays ranging from 9.0 ns to 35 ns depending on load capacitance. It includes triple diode protection on control inputs and offers linearized transfer characteristics.
Analog Switches, Multiplexers, Demultiplexers Feature Summary
- Triple diode protection integrated on all control inputs for enhanced robustness.
- Break before make switching function ensures signal integrity during channel transitions.
- Linearized transfer characteristics provide consistent performance across the analog signal range.
- Low-noise design with typical noise density of 12 nV/√Hz at frequencies greater than or equal to 1.0 kHz.
Analog Switches, Multiplexers, Demultiplexers Applications
- Signal routing in data acquisition systems requiring multi-channel selection.
- Audio signal processing applications utilizing the device's low-noise characteristics.
- Test and measurement equipment needing precise analog switching capabilities.
Analog Switches, Multiplexers, Demultiplexers Procurement Notes
Verify the ordering suffix 'FG' against official documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and Pb-Free designation as indicated by the 'G' suffix. Ensure the component meets AEC-Q100 requirements if automotive qualification is necessary, noting that NLV prefix variants are specifically designated for such applications.
Analog Switches, Multiplexers, Demultiplexers Selection Notes
Select the MC14051BFG when an 8-channel multiplexer configuration is required. Consider the HC4051 variant if lower ON resistance is critical for the application. Verify that the supply voltage range between VDD and VEE does not exceed 18.0 V. Ensure unused inputs are tied to appropriate logic levels to prevent undefined states.
Analog Switches, Multiplexers, Demultiplexers Part Context
The MC14051BFG belongs to the MC14051B/D family of analog multiplexers manufactured by onsemi. This series is designed as a pin-for-pin replacement for CD4051 devices. The component is part of a broader lineup that includes the MC14052B (DP4T) and MC14053B (Triple SPDT), sharing similar CMOS construction and operational characteristics.
Analog Switches, Multiplexers, Demultiplexers Replacement Considerations
The MC14051BFG serves as a direct pin-for-pin replacement for the CD4051. For applications requiring lower ON resistance, the HC4051 High-Speed CMOS device is recommended. Other compatible options within the same family include the MC14052B and MC14053B for different channel configurations.
