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.
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.
Applications
- Data acquisition systems
- Audio signal routing
- Medical instrumentation
- ATE systems
- Battery powered systems
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.
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.
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.
