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.
Feature Summary
- Break-before-make switching prevents momentary shorting of inputs during channel transitions.
- TTL and CMOS compatible digital decode circuitry allows direct interfacing with standard logic families.
- Enable (EN) input facilitates resetting the multiplexer to all switches off for stacking multiple devices.
- Epitaxial layer design prevents latch-up associated with older CMOS technologies.
Applications
- High-speed data acquisition systems
- Audio signal switching and routing
- Automatic test equipment (ATE)
- Medical instrumentation
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.
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.
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.
