MC14551BFG

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14551BFG is a digitally controlled analog switch implementing four single-pole double-throw (SPDT) channels in a 16-SOEIAJ package. It operates on a single supply voltage ranging from 3.0 V to 18 V, with an analog signal range matching the supply span. Key electrical parameters include a maximum on-resistance of 280 Ω at 15 V and a bandwidth of 17 MHz. The device features triple diode protection on control inputs, low off-channel leakage current of 100 nA, and linearized transfer characteristics for accurate signal routing.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Triple diode protection integrated on all digital control input pins
• Linearized transfer characteristics ensuring consistent signal integrity across the full voltage range
• Break-before-make switching function prevents signal overlap during channel transitions

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in data acquisition systems
• Audio signal path switching
• Test and measurement equipment multiplexing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'F' corresponds to the SOEIAJ-16 package configuration before procurement. Confirm RoHS compliance status as required by specific project regulations. Ensure static discharge precautions are implemented during handling due to high-impedance CMOS inputs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPDT analog switch with wide supply voltage compatibility is required. Consider the 280 Ω on-resistance limit for applications demanding lower insertion loss, where high-speed alternatives may be necessary. Verify that the 16-SOEIAJ footprint aligns with the target PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MC14551B family of quad 2-channel analog multiplexers. The 'F' suffix specifically designates the SOEIAJ-16 surface mount package variant. It shares functional specifications with other suffixes like 'D' (SOIC) and 'P' (PDIP), differing primarily in physical dimensions and mounting style.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include MC14551BDG and MC14551BCPG. Verify package dimensions and lead configurations match the existing board layout when substituting.
