DG412HSDY-T1-E3

Overview

The DG412HSDY-T1-E3 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 supports dual supply voltages up to ±15 V and single supplies up to 44 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. It operates within a temperature range of -40 °C to +85 °C.

Feature Summary

• High-voltage silico gate process construction with epitaxial layer preventing latchup
• Break-before-make switching action to prevent signal shorting during transitions
• TTL and CMOS logic compatible control inputs for simple interfacing
• Low power dissipation suitable for portable and battery-powered applications

Applications

• Precision automatic test equipment
• Precision data acquisition systems
• Communication systems
• Battery powered systems
• Computer peripherals

Procurement Notes

Verify the specific suffix T1 indicates tape and reel packaging when ordering. Confirm RoHS compliance status via the E3 designation. Ensure the narrow SOIC-16 footprint matches the PCB layout requirements. Check for any recent product change notices that might affect pinout or specifications.

Selection Notes

Select this component for applications requiring fast switching speeds and low distortion. Compare against DG411HS if non-inverted logic is needed, as DG412HS responds to opposite control logic. Consider DG413HS if mixed normally open and closed configurations are required. Verify power dissipation limits against thermal derating curves for high ambient temperatures.

Part Context

This part belongs to the DG411HS/DG412HS/DG413HS family of precision analog switches. The DG412HS variant specifically utilizes inverted logic compared to the DG411HS. The HSDY suffix denotes the 16-pin Narrow SOIC package, while T1 indicates reel packaging and E3 signifies lead-free/RoHS compliance.

FAQ

What is the logic sense of the DG412HS series?

The DG412HS responds to opposite control logic compared to the DG411HS. A logic '0' turns the switch OFF, and a logic '1' turns it ON.

What is the maximum supply voltage rating?

The absolute maximum rating for V+ to V- is 44 V. The analog signal range can extend up to ±15 V with a ±15 V supply.

Does the device support break-before-make switching?

Yes, the DG412HS features break-before-make switching action, which prevents signal shorting during channel transitions.
