DG418LEDY-T1-GE4

Overview

The DG418LEDY-T1-GE4 is a single-channel SPST analog switch from the Vishay Siliconix DG418LE series, housed in an 8-pin narrow SOIC package. It operates on a single supply of +3 V to +16 V or dual supplies of ±3 V to ±8 V. The device features a typical drain-source on-resistance of 6 Ω and maximum limits up to 9 Ω at room temperature. Switching speeds include a turn-on time of 20 ns and turn-off time of 15 ns. It supports CMOS/TTL logic inputs, exhibits low power dissipation of 400 mW, and functions within a temperature range of -40 °C to +85 °C.

Feature Summary

CMOS technology enabling fast switching with low power consumption
Low on-resistance for minimal signal attenuation
Compatible with standard CMOS and TTL logic levels
Capable of handling analog signals across the full supply voltage range

Applications

Data acquisition systems
Medical instruments
Precision instruments
Communications systems
Automated test equipment

Procurement Notes

Verify the specific suffix 'T1' indicates tape-and-reel packaging and 'GE4' confirms RoHS compliance before ordering. Confirm that the narrow SOIC footprint matches the target PCB layout dimensions. Ensure the design accounts for the specified thermal derating requirements above 25 °C to maintain reliability under continuous operation.

Selection Notes

Select this component when a single-pole single-throw configuration is required for low-voltage applications. The DG418LE serves as a lower-voltage alternative to the standard DG418, offering compatibility with +3 V and +5 V logic systems. Verify that the 6 Ω on-resistance meets the signal integrity requirements of the specific application circuit.

Part Context

This part belongs to the DG417LE/DG418LE/DG419LE family, which are pin-for-pin compatible companion devices to the industry-standard DG417/418/419 switches. The LE series is specifically optimized for lower voltage operation compared to its predecessors while maintaining similar functional characteristics and package options.
