DG401BDY-E3

Overview

The DG401BDY-E3 is a low-power, high-speed CMOS analog switch manufactured by Vishay Siliconix. It contains two independent single-pole single-throw (SPST) switches housed in a 16-pin narrow SOIC package. The device supports a maximum supply voltage of 44 V and an analog signal range of ±15 V. Key electrical parameters include a typical on-resistance of 23 Ω with a maximum of 45 Ω at room temperature, rising to 55 Ω across the full operating temperature range. Turn-on time is typically 100 ns with a maximum of 150 ns, while turn-off time is typically 60 ns with a maximum of 100 ns. Leakage current is specified at a maximum of 0.5 nA when off and 1 nA when on at room temperature.

Feature Summary

High-speed switching capability combined with low power consumption suitable for portable applications
TTL and CMOS logic compatible input control
Capable of conducting equally well in both directions when on
Blocks up to 30 V peak-to-peak when off

Applications

Audio and video switching
Sample-and-hold circuits
Test equipment
PBX and PABX systems

Procurement Notes

Verify the component status before procurement as the DG401B series may be subject to discontinuation or obsolescence notices from the manufacturer. Confirm that the -E3 suffix correctly denotes lead-free matte tin terminations if environmental compliance is required. Ensure the narrow SOIC package dimensions match the target PCB footprint requirements.

Selection Notes

Select this component when dual SPST switching is required within a single package. Verify that the 45 Ω maximum on-resistance meets the application's signal integrity needs. Ensure the 44 V absolute maximum rating accommodates the system's supply voltages. Consider the 150 ns maximum turn-on time for timing-sensitive designs.

Part Context

The DG401BDY-E3 belongs to the DG401B/DG403B/DG405B family of monolithic analog switches. These devices are designed as replacements for the earlier DG401/DG403/DG405 series, offering improved performance through Vishay Siliconix's proprietary high-voltage silicon gate process. The family shares similar electrical characteristics but differs in channel configuration.
