MC14551BF

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14551BF is a digitally controlled analog switch implementing four independent SPDT solid-state switches. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc, supporting analog signals across the complete supply span. Key electrical parameters include a maximum on-resistance (Ron) of 280 Ω at 15 V and a typical bandwidth of 17 MHz. The device features very low off-channel leakage current of ±100 nA and triple diode protection on all control inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized channels as this part number may be subject to obsolescence or replacement by newer series. Confirm package suffix 'F' corresponds to the SOEIAJ-16 housing. Review RoHS compliance status prior to integration into regulated assemblies.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high isolation and wide dynamic range are required. Ensure the application voltage does not exceed the 18 Vdc limit. Consider alternative HC-series devices if lower on-resistance is critical, as this CMOS implementation prioritizes leakage performance over conduction loss.

Analog Switches, Multiplexers, Demultiplexers Part Context
