Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm the lead-free status and tape-and-reel packaging format. Ensure that the required quantity aligns with standard reel sizes if bulk procurement is intended. Cross-reference the RoHS compliance details directly with the official datasheet to meet environmental regulatory requirements for the target assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring low-voltage operation between 1.8 V and 5.5 V. The sub-ohm on-resistance makes it suitable for applications demanding high accuracy and minimal signal attenuation. Verify that the logic input thresholds are compatible with the control signals, as the device supports 1.6-V logic compatibility for interfacing with low-voltage DSPs.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG series of analog switches produced by Vishay Siliconix. It utilizes a high-density low-voltage CMOS process with an epitaxial layer to prevent latchup. The DG2031 is specifically engineered for battery-powered applications where space saving and low power consumption are critical design constraints.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The standard version DG2031DQ-T1 serves as the non-compliant predecessor. For direct functional replacement, verify pinout compatibility with other dual SPDT switches in the DG family, such as the DG2026, while confirming that their respective on-resistance and voltage specifications meet the circuit requirements.
