DG419DY-T1

Overview

The DG419DY-T1-E3 is a precision CMOS analog switch manufactured by Vishay Siliconix, housed in an 8-lead narrow SOIC package. It features a single SPDT configuration with a maximum on-resistance of 35 Ohms and a supply voltage range from 13 V to 44 V. The device supports dual supplies between -15 V and +15 V, operates within a temperature range of -40 °C to +85 °C, and exhibits a maximum turn-on time of 175 ns. Power dissipation is rated at 400 mW, with a maximum supply current of 1 uA.

Feature Summary

Break-before-make switching action ensures reliable signal routing without shorting outputs.
Ultra-low power consumption suitable for battery-operated and portable systems.
TTL and CMOS logic compatibility simplifies digital control interfacing.

Applications

Precision test equipment
Sample-and-hold circuits
Battery powered systems

Procurement Notes

Verify the complete part number including the suffix '-E3' to confirm RoHS compliance status. Ensure the ordering suffix matches the required tape and reel packaging format for automated assembly processes. Cross-reference the manufacturer's latest documentation to validate any revisions to the pinout or electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when a single-pole double-throw (SPDT) topology is required for analog signal routing. The narrow SOIC package is appropriate for applications demanding high board space efficiency. Verify that the maximum supply voltage and on-resistance limits align with the specific circuit requirements and operating temperature conditions.

Part Context

This device belongs to the DG417 series of monolithic CMOS analog switches. It shares the same physical package and general performance characteristics as the DG417 and DG418 models, differing primarily in its internal SPDT configuration compared to the SPST configurations of the other variants in the family.

FAQ

What is the guaranteed switching characteristic for the DG419?

The DG419 guarantees break-before-make switching action, which prevents the simultaneous connection of both common terminals during state transitions.

How does the DG419 handle signals exceeding the supply rails?

Signals on the source or drain pins exceeding the positive or negative supply levels are clamped by internal diodes, requiring the forward diode current to be limited to the maximum ratings.
