DG412HSDY-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412HSDY-T1 is a precision monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix. It features four independent switches in a 16-pin Narrow SOIC package, designed for high-speed switching of precision analog signals with low power consumption. The device operates on single or dual supplies, supporting a maximum supply voltage of 44 V and an analog signal range of ±15 V. Key electrical parameters include a maximum on-resistance of 35 Ω, a turn-on time of 105 ns, and a turn-off time of 80 ns at room temperature under standard test conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T1' indicates tape and reel packaging configuration. Confirm RoHS compliance status as the base model may have non-compliant variants. Check current production lifecycle status, as older revisions may be discontinued. Validate that the narrow SOIC-16 footprint matches the target PCB layout requirements before finalizing orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when bidirectional analog signal routing is required within a ±15 V range. Ensure the control logic aligns with the DG412HS truth table, which is opposite to the DG411HS series. Verify thermal derating calculations for the SOIC-16 package if operating near the upper temperature limit. Consider the charge injection specifications for high-precision signal integrity requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG411HS/DG412HS/DG413HS family of precision analog switches. The DG412HS variant specifically utilizes control logic opposite to the DG411HS. The 'DY' suffix denotes the 16-pin Narrow SOIC package, while 'T1' specifies the reel packaging format. These devices are built on a high-voltage silicon gate process optimized for low power and high speed.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG411HSDY-T1-E3: Compatible alternative with opposite control logic sense. DG412HSDN-T1-E4: Same electrical performance but housed in a 16-QFN package instead of SOIC-16.
