Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type and RoHS compliance status. Ensure that the selected variant matches the required lead-free specifications and reel or cut tape format for your assembly line. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single-channel, normally open analog switch is required for high-voltage applications up to 44 V. The DG418 offers complementary logic control relative to the DG417. Evaluate the 35 Ohm on-resistance and 175 ns switching speed against system requirements. Confirm compatibility with standard SOIC-8 footprints during PCB layout design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the DG417/DG418/DG419 family of precision CMOS analog switches. While the DG417 provides a normally closed configuration and the DG419 offers a single-pole double-throw (SPDT) arrangement, the DG418 specifically provides a single-pole single-throw (SPST) normally open function. All variants share similar electrical characteristics and are designed for portable and industrial applications.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic control behavior of the DG418?

The DG418 responds to opposite control logic levels compared to the DG417. A logic '0' turns the switch off, while a logic '1' turns it on.

Does the DG418 support break-before-make switching?

No, break-before-make switching is guaranteed only for the DG419 variant. The DG418 does not feature this characteristic.

What is the maximum supply voltage rating?

The absolute maximum rating for the positive supply voltage (V+) is 44 V.
