Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'BK' against official manufacturer documentation to confirm package type and material composition. Ensure that the procurement source provides valid RoHS compliance certificates as required for modern manufacturing standards. Cross-reference the part number with the latest datasheet revision history to confirm availability status and any potential obsolescence notices before finalizing orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single SPDT switch with 50-ohm on-resistance is required in a ceramic DIP package. Consider the ±5V to ±18V dual supply range for appropriate voltage headroom. Evaluate the 12pC charge injection parameter against application sensitivity requirements. Confirm that the 14-pin CerDIP footprint aligns with existing PCB layout constraints and thermal management needs.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG301ABK belongs to the DG300 series of analog switches, which are characterized by low on-resistance and fast switching speeds. This series is widely used in industrial and communication equipment for signal routing. The ABK variant specifically denotes the ceramic dual-in-line package option, offering robustness for environments where standard plastic packages may be insufficient.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG301ACWE+ is a documented equivalent within the same product family, offering identical electrical specifications but in a 16-SOIC surface-mount package. Verify pinout compatibility and mechanical clearance differences between the 14-pin CerDIP and 16-pin SOIC formats before substitution.
