Overview
The DG406DW 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 a maximum supply voltage of 44 V and supports dual supplies up to ±20 V or a single 12 V supply. Key electrical parameters include a typical on-resistance of 50 Ω, a maximum of 125 Ω, and a transition time of 200 ns. It features low charge injection of 15 pC and an off-isolation of -69 dB. The component is housed in a 28-pin widebody SOIC package and functions within a temperature range of -40 °C to +85 °C.
Feature Summary
- Break-before-make switching action prevents momentary shorting of inputs.
- TTL-compatible control inputs across the full operating temperature range.
- Epitaxial layer design prevents latchup for increased ruggedness.
- Enable function allows resetting all switches to the off state.
Applications
- High-speed data acquisition systems
- Audio signal switching and routing
- Automated test equipment (ATE) systems
- Avionics applications
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging and compliance status. The '-T1' suffix indicates tape and reel packaging, while its absence typically denotes tube packaging. Confirm RoHS compliance requirements for the specific procurement batch. Ensure the selected variant matches the required lead-free specifications for the intended assembly process.
Selection Notes
Select this component when a high channel count is required for single-ended signal routing. Verify that the 44 V absolute maximum rating aligns with the system's power supply rails. Consider the 125 Ω maximum on-resistance limit for applications requiring lower signal attenuation. Ensure the 28-pin widebody SOIC footprint fits the available PCB layout constraints.
Part Context
This part belongs to the DG406/DG407 series of high-performance CMOS analog multiplexers. The DG406 specifically provides a 16:1 configuration, whereas the DG407 offers a dual 8:1 differential configuration. Both share similar performance characteristics and are designed for applications demanding low power dissipation and high accuracy.
Replacement Considerations
DG406DW-E3 is the non-tape-and-reel equivalent in the same package. DG406DN-T1-E3 serves as a PLCC-28 alternative. Cross-model substitution requires verifying pin compatibility and ensuring the replacement meets the required on-resistance and voltage ratings.
