DG407BDW-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG407BDW-E3 is a dual 8-channel high-performance CMOS analog multiplexer manufactured by Vishay Siliconix. It selects one of eight differential inputs to a common differential output using 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 45 Ω, a transition time of 115 ns, and charge injection of 11 pC. It features TTL-compatible control inputs, an enable function for stacking devices, and break-before-make switching action. The component is housed in a 28-pin widebody SOIC package and supports an operating temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against official documentation to confirm compliance status and termination finish. The -E3 designation indicates lead-free and RoHS-compliant manufacturing. Confirm that the widebody SOIC package matches the target PCB footprint requirements before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when differential signal routing is required within a multiplexed architecture. Ensure the application voltage does not exceed the absolute maximum rating of 44 V between supply rails. Verify that the 45 Ω on-resistance meets the signal integrity requirements for the specific analog signals being routed.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG406B/DG407B series of monolithic CMOS analog multiplexers. It serves as a drop-in replacement for legacy DG506A and DG507A devices while offering improved performance metrics such as lower on-resistance and faster transition times. The series utilizes a 44 V silicon-gate CMOS process for enhanced ruggedness.
