MC14551BDR2G

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14551BDR2G is a quad dual-channel analog multiplexer/demultiplexer manufactured by onsemi. It operates within a supply voltage range of 3 V to 18 V and supports surface-mount installation in an SOIC-16 package. The device features four independent switches, each configurable as either single-pole double-throw (SPDT) or double-pole four-throw (DP4T). It exhibits a maximum channel-on resistance of 600 Ω and a leakage current of 500 nA at typical conditions. The component is rated for operation between -40°C and +125°C, ensuring reliability in industrial environments.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'D' confirms the SOIC-16 package variant and 'R2G' indicates tape-and-reel packaging with RoHS compliance. Confirm the manufacturer date code aligns with project requirements. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity. Cross-reference the datasheet revision level to verify pinout consistency with existing designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when multiple analog signals require switching within a single IC footprint. The wide voltage range accommodates various logic families. Consider the on-resistance variation across temperature if signal integrity is critical. Compare against the MC14051 family for simpler single-channel applications or higher speed requirements where lower capacitance is needed.
