DG406BDN-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG406BDN-T1-E3 is a 16-channel single-ended 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 ±5 V to ±20 V, or a single 12 V supply. Key electrical parameters include a maximum drain-source on-resistance of 74 Ω and a typical charge injection of 11 pC. Transition time reaches 163 ns under single-supply conditions. The component is housed in a 28-pin PLCC package and supports an operating temperature range from -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix configuration against current datasheets before procurement. The -T1 suffix indicates tape and reel packaging, while -E3 denotes lead-free and RoHS compliance. Confirm that the 28-pin PLCC package matches the target PCB footprint requirements. Ensure the voltage ratings align with the system's power supply architecture.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a high channel count is required for single-ended signals. Verify that the 74 Ω maximum on-resistance meets the application's signal integrity needs. Consider the 163 ns transition time for timing-sensitive designs. Ensure the 28-pin PLCC package is compatible with the assembly process and available board space constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG406B series of high-performance CMOS analog multiplexers. It shares functional similarities with the DG407B but differs in channel configuration and input type. The DG406B provides a 16:1 single-ended configuration, whereas the DG407B offers dual 8:1 differential channels. Both utilize the same 44 V silicon-gate CMOS process technology.
