Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and tape-and-reel availability. Confirm RoHS compliance status through the latest datasheet revision. Ensure the ordering part number matches the required thermal grade and packaging format for the intended production volume.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel analog switch with moderate speed and wide voltage tolerance is required. Compare the 175 Ohm on-resistance limit against circuit requirements to ensure signal integrity is maintained. Verify that the 16-pin SOIC-Narrow footprint fits the PCB layout constraints and that the commercial temperature range meets environmental conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG408 series of improved CMOS multiplexer switches. It serves as a legacy component within the Analog Devices portfolio, succeeding earlier iterations of CMOS analog switches. The device provides a cost-effective solution for general-purpose signal switching in embedded systems where high-speed performance is not the primary constraint.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Consult official cross-reference lists for direct pin-compatible alternatives such as the DG408DY+T or DG408EUE+. Verify that substitute parts maintain identical on-resistance, leakage current, and supply voltage specifications before integration.
