DG406BDJ

Overview

The DG406BDJ is a CMOS analog multiplexer manufactured by Vishay Siliconix, housed in a 28-pin PDIP package. It features a 1x16:1 configuration with single-ended switching capabilities. The device operates on a minimum supply voltage of 7.5 V and supports up to 36 V single supply or ±20 V dual supply. Key electrical parameters include a maximum on-resistance of 100 Ohms, a typical off-isolation of -69 dB, and a maximum power dissipation of 625 mW. Switching performance specifies a maximum turn-on time of 125 ns and a turn-off time of 94 ns. The component functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• CMOS technology ensures low power consumption and high input impedance for signal integrity.
• High isolation characteristics minimize crosstalk between channels during operation.
• Robust mechanical design accommodates through-hole mounting for durable circuit board integration.

Applications

• Data acquisition systems requiring multi-channel signal routing
• Industrial process control instrumentation
• Automotive electronic testing equipment

Procurement Notes

Verify the specific suffix requirements against current manufacturer documentation, as legacy part numbers may have updated compliance statuses or pinout variations. Confirm availability status directly with authorized distributors, as this component may be subject to discontinuation notices or limited stock constraints depending on the region and supplier.

Selection Notes

Select this component when a 16-channel single-ended multiplexer is required in a through-hole DIP package. Ensure the application voltage does not exceed the 36 V single-supply limit. Consider thermal management if power dissipation approaches the 625 mW limit, particularly in enclosed environments where ambient temperatures approach the upper operational threshold.

Part Context

This part belongs to the DG406B series of analog multiplexers from Vishay Siliconix. It shares functional similarities with other members of the family but differs in packaging and specific electrical tolerances. The DG406BDJ specifically denotes the through-hole PDIP variant, distinguishing it from surface-mount options like the DW or DN series.

Replacement Considerations

Direct replacements include DG406BDN-E3 (PLCC-28) and DG406BDW-E3 (SOIC-Wide-28). Verify pin compatibility and thermal characteristics before substitution. Other series members may require schematic adjustments due to differing channel counts or package footprints.
