DG412DY-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412DY-T1 is a quad single-pole single-throw (SPST) analog switch IC manufactured by Vishay Siliconix. It features a CMOS logic interface and is housed in a 16-pin SOIC surface-mount package. The device supports dual supply voltages ranging from ±5 V to ±20 V, with a maximum on-resistance of 35 Ohms. Switching performance includes a maximum turn-on time of 175 ns and a maximum turn-off time of 145 ns. It operates within a temperature range of -40°C to +85°C and dissipates up to 600 mW of power.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix T1 indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official datasheets or manufacturer declarations, as environmental certifications may vary by production batch. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring four independent analog switches in a compact SOIC-16 footprint. Compare against the DG412DQ variant if a TSSOP package is preferred for space-constrained designs. Verify that the required supply voltage range aligns with the ±5 V to ±20 V specification before integration into the circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG412 series of enhanced analog switches from Vishay Siliconix. The series is characterized by improved operating voltage ranges and lower leakage limits compared to earlier generations. The DG412DY-T1 specifically denotes the standard on-resistance version packaged in reels for automated assembly processes.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG412DQ-T1-E3 serves as a pin-compatible alternative utilizing a TSSOP-16 package instead of SOIC-16. Designers must verify board layout compatibility due to the difference in package dimensions and thermal characteristics between the two form factors.
