DG419LEDY-T1-GE4

Overview

The DG419LEDY-T1-GE4 is a Vishay Siliconix CMOS analog switch featuring one SPDT channel in an 8-pin SOIC package. It operates on single supplies from +3 V to +16 V or dual supplies from ±3 V to ±8 V. The device exhibits a maximum on-resistance of 15 Ω and supports a continuous current of 30 mA. Switching times reach a maximum of 38 ns for turn-on and 45 ns for turn-off. It functions within a temperature range of -40 °C to +85 °C with a power dissipation rating of 400 mW.

Feature Summary

CMOS technology providing low power dissipation and fast switching speeds
Break-before-make switching action prevents signal shorting during transitions
Control logic input tolerance allows operation above the positive supply rail
Compatible with standard CMOS and TTL logic families

Applications

Data acquisition systems
Medical instruments
Precision instrumentation
Automated test equipment
Audio and video signal routing

Procurement Notes

Verify the specific suffix 'T1-GE4' against the manufacturer's ordering information to confirm tape-and-reel packaging and RoHS compliance status. Ensure the component matches the narrow SOIC-8 footprint dimensions specified in the datasheet. Confirm that the operating voltage requirements align with the single or dual supply specifications provided in the electrical characteristics tables.

Selection Notes

Select this component when a single-pole double-throw configuration is required for low-voltage applications. The DG419LE variant offers lower on-resistance compared to older industry standards while maintaining pin compatibility. Consider the break-before-make timing if sequential switching is critical to avoid transient glitches in the signal path.

Part Context

This part belongs to the DG417LE, DG418LE, and DG419LE family of precision analog switches. These devices serve as lower-voltage, pin-for-pin compatible replacements for the legacy DG417, DG418, and DG419 series. They utilize advanced CMOS technology to achieve improved performance metrics at reduced supply voltages.
