DG406BDN

Overview

The DG406BDN is a 16-channel single-ended analog multiplexer manufactured by Vishay Siliconix. It connects one of sixteen inputs to a common output via a 4-bit binary address. The device operates with supply voltages ranging from ±5 V to ±20 V, or a single supply up to 40 V. Key electrical parameters include an on-resistance of 45 Ω, transition time of 115 ns, and charge injection of 11 pC. It features TTL-compatible control inputs and an enable function for stacking multiple devices.

Feature Summary

• Break-before-make switching action prevents momentary shorting of inputs.
• TTL-compatible digital control inputs across the full operating temperature range.
• Enable function allows resetting all switches to the off state for system stacking.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and compliance status. The base model designation may correspond to different physical packages such as PLCC-28 or SOIC-28 depending on the suffix. Confirm availability through authorized distributors as production status can change without notice.

Selection Notes

Select this component when a high channel count and low on-resistance are required for precision analog signal routing. Ensure the application voltage does not exceed the absolute maximum ratings of 44 V between supplies. Verify that the 4-bit address interface matches the system logic levels and that the power dissipation limits within the chosen package are sufficient for the thermal environment.

Part Context

This part belongs to the DG406B/DG407B family of high-performance CMOS analog multiplexers. The DG406B variant specifically provides a 16:1 configuration, whereas the DG407B offers dual 8:1 differential channels. Both share the same silicon-gate CMOS process technology designed for ruggedness and low power consumption.

FAQ

What is the purpose of the Enable (EN) pin?

The Enable function allows the user to reset the multiplexer to all switches off, which facilitates stacking several devices in a system.

How does the device handle input signals exceeding the supply rails?

Signals on the source pins exceeding the power supply rails will be clamped by internal diodes. The forward diode current must be limited to the maximum current ratings.

What is the typical off-isolation performance?

The typical off-isolation is -86 dB at 1 MHz with a 50 Ω load.
