DG406DN-T1-E3

Overview

The DG406DN-T1-E3 is a 16-channel single-ended CMOS analog multiplexer manufactured by Vishay Siliconix. It connects one of sixteen inputs to a common output based on a 4-bit binary address. The device operates with supply voltages ranging from 7.5 V to 44 V for single supply, or ±5 V to ±20 V for dual supply configurations. Key electrical parameters include a maximum on-resistance of 120 Ω, a transition time of up to 350 ns, and an off-isolation of -69 dB at 100 kHz. It features TTL-compatible control inputs, break-before-make switching action, and an enable function. The component is housed in a 28-pin PLCC package and supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Break-before-make switching action prevents momentary shorting of inputs during channel transitions.
• TTL-compatible control inputs, address lines, and enable functions across the full specified operating temperature range.
• On-channel conducts current equally well in both directions while blocking voltages up to the power supply rails in the off state.
• Epitaxial layer design prevents latchup under stress conditions.

Applications

• High-speed data acquisition systems
• Audio signal switching and routing
• Automated test equipment (ATE) systems
• Avionics applications

Procurement Notes

Verify the specific suffix configuration when ordering. The -T1 designation indicates tape and reel packaging, while -E3 confirms lead-free and RoHS compliance. Confirm that the PLCC-28 package matches the target footprint requirements. Ensure the voltage ratings align with the system's single or dual supply architecture before procurement.

Selection Notes

Select this component for applications requiring high channel density in a compact surface-mount package. The 16:1 configuration reduces board space compared to lower-density alternatives. Verify that the 120 Ω maximum on-resistance meets the signal integrity requirements of the specific application circuit. Consider the 350 ns transition time when determining maximum sampling rates for the data acquisition chain.

Part Context

This part belongs to the DG406/DG407 series of high-performance CMOS analog multiplexers. The DG406 variant specifically provides 16 single-ended channels, whereas the DG407 offers 8 differential pairs. Both share the same 28-pin PLCC package option and utilize the same 44 V silicon-gate CMOS process technology designed for ruggedness and low power consumption.

Replacement Considerations

DG406DW-E3 is a pin-compatible alternative in a wide-body SOIC package. DG406DN+ is available from Analog Devices/Maxim Integrated in the same PLCC-28 package but may have different electrical specifications.
