DG406BDW

Overview

The DG406BDW-E3 is a high-performance CMOS analog multiplexer manufactured by Vishay Siliconix. It features a 16-channel single-ended configuration, connecting one of sixteen inputs to a common output based on a 4-bit binary address. The device operates with supply voltages ranging from ±5 V to ±20 V or a single 12 V supply. Key electrical parameters include a maximum on-resistance of 74 Ω, a transition time of up to 163 ns, and an off-isolation of -86 dB at 1 MHz. It utilizes a wide-body SOIC-28 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 temperature range.
• Epitaxial layer design prevents latchup under extreme voltage conditions.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance status and termination finish. The '-E3' designation indicates lead-free and RoHS-compliant manufacturing. Confirm that the wide-body SOIC package matches the intended PCB footprint requirements for the target application.

Selection Notes

Select this component when a 16-channel single-ended analog switch is required with low charge injection and fast transition times. Ensure the system power supply falls within the ±5 V to ±20 V dual supply or 12 V single supply limits. Verify that the wide-body SOIC-28 package dimensions are compatible with the available board space and assembly processes.

Part Context

This part belongs to the DG406B/DG407B family of high-performance CMOS analog multiplexers. The DG406B variant specifically provides 16 single-ended channels, whereas the DG407B offers dual 8-channel differential configurations. Both share identical core performance characteristics and pinout structures within their respective channel counts.

Replacement Considerations

DG406BDN-T1-E3: Identical functional specifications utilizing a PLCC-28 surface-mount package instead of the wide-body SOIC format.

FAQ

How does the break-before-make feature benefit circuit operation?

It ensures that the previous channel disconnects before the new channel connects, preventing momentary shorting of inputs and reducing glitching in the signal path.

What is the maximum absolute voltage rating for the device?

The absolute maximum voltage rating between V+ and V- is extended to 44 V due to the 44 V silicon-gate CMOS process used in its construction.

Is the device suitable for battery-operated applications?

Yes, the low power dissipation and single-supply capability make it ideal for battery-operated and remote instrumentation applications.
