DG1412EN-T1-GE4

Overview

The DG1412EN-T1-GE4 is a precision monolithic quad single-pole single-throw (SPST) normally open CMOS analog switch manufactured by Vishay Siliconix. It operates from single supplies of 4.5 V to 24 V or dual supplies of ±4.5 V to ±16.5 V. The device features a typical on-resistance of 1.5 Ω with a maximum flatness of 0.3 Ω and channel-to-channel matching of 0.08 Ω. It supports rail-to-rail signal handling, offers low charge injection of -20 pC, and provides off-isolation of -80 dB at 100 kHz. The component is housed in a 16-pin QFN package measuring 4 mm by 4 mm.

Feature Summary

• Quad SPST configuration with normally open logic sense
• Low on-resistance with high linearity over the full signal range
• Rail-to-rail analog signal handling capability
• Compatible with standard TTL and CMOS logic levels

Applications

• Data acquisition systems
• Industrial control and automation
• Medical instrumentation
• Audio and video signal switching
• Relay replacement circuits

Procurement Notes

Verify the specific suffix EN-T1-GE4 to confirm the QFN-16 package and tape-and-reel packaging format. Ensure the ordering code matches the required temperature range of -40 °C to +125 °C. Cross-reference the manufacturer part number against official Vishay documentation to validate authenticity and revision status before procurement.

Selection Notes

Select this component for applications requiring four independent normally open switches with low distortion. Verify that the supply voltage range aligns with the system's power rails. Consider the thermal resistance of the QFN package if operating near the upper temperature limits. Confirm that the logic input thresholds meet the driving circuit requirements.

Part Context

This part belongs to the DG141x family, which includes the DG1411 (normally closed) and DG1413 (mixed NC/NO). All variants share identical electrical characteristics and pinouts but differ in their default switch states. The DG1412 specifically provides four normally open channels, distinguishing it from the other members of the series.

FAQ

What is the logic sense for the DG1412?

The DG1412 is a normally open switch, meaning the switch closes when the digital input is high (Logic 1) and opens when the input is low (Logic 0).

Does the DG1412 require a separate VL logic supply?

No, the device does not require a separate VL logic supply. It utilizes an internal level shifter to ensure compatibility with low-voltage TTL and CMOS inputs.

What is the maximum supply voltage rating?

The absolute maximum rating for the supply voltage difference (V+ to V-) is 35 V. The recommended operating range extends up to ±16.5 V.
