DG407BDW-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG407BDW-T1-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 supply up to 40 V. Key electrical parameters include a maximum on-resistance of 74 Ω, a transition time of 161 ns, and charge injection of 11 pC. It features an enable function for stacking devices and TTL-compatible control inputs.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Break-before-make switching action prevents momentary shorting of inputs.
• On channel conducts current equally well in both directions.
• In the off state each channel blocks voltages up to the power supply rails.
• Enable (EN) function allows resetting the multiplexer to all switches off.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against the official Vishay datasheet document number 72552. Confirm that the package matches the 28-pin widebody SOIC format and that the suffix -T1 indicates tape and reel packaging. Ensure the -E3 designation confirms lead-free and RoHS compliance as specified in the ordering information section.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when differential signal routing is required within a 16-channel array architecture. The DG407B serves as the differential counterpart to the single-ended DG406B. Verify that the 74 Ω maximum on-resistance and 161 ns transition time meet the system's bandwidth and speed requirements under the intended supply voltage conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG406B/DG407B series of monolithic CMOS analog multiplexers. It is designed as a drop-in replacement for older DG506A and DG507A series devices. The series utilizes a 44 V silicon-gate CMOS process with an epitaxial layer to prevent latch-up, offering improved performance over previous generations.
