Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix FG corresponds to the SOEIAJ-16 package configuration as documented in the official onsemi ordering information table. Confirm RoHS compliance status and lead-free packaging details directly from the manufacturer's current datasheet revision before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4-channel analog switch is required with high voltage tolerance up to 18 V. Ensure the application demands low leakage current and linear transfer characteristics. Verify that the SOEIAJ-16 surface mount package fits the PCB layout constraints compared to alternative PDIP or SOIC packages.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MC1405xB series of CMOS analog multiplexers, which also includes the MC14051B (8-channel) and MC14053B (triple 2-channel). These devices are designed as pin-for-pin replacements for legacy CD4051, CD4052, and CD4053 components, maintaining compatibility while offering improved performance metrics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MC14052BDG serves as a surface-mount alternative in the SOIC-16 package. For lower on-resistance requirements, consider the HC4052 high-speed CMOS device. Verify pin compatibility and electrical parameter differences before substituting.
