Overview
The DG509BEJ-E3 is a dual 4-channel differential analog multiplexer manufactured by Vishay Siliconix. It connects one of four differential inputs to a common dual output via a 2-bit binary address (A0, A1). The device operates with single or dual power supplies ranging from ±5 V to ±20 V, or up to 44 V single supply. Key electrical parameters include a maximum on-resistance of 380 Ω, a -3 dB bandwidth of 250 MHz, and an enable turn-on time of 250 ns. It features TTL-compatible control inputs, break-before-make switching, and operates within a temperature range of -40 °C to +125 °C in a 16-lead PDIP package.
Feature Summary
- Break-before-make switching action prevents momentary crosstalk between adjacent channels.
- TTL-compatible control inputs ensure compatibility across the full specified operating temperature range.
- Enhanced SG-II CMOS process achieves reduced charge injection and minimized parasitic capacitance.
- Epitaxial layer prevents latch-up for increased ruggedness.
Applications
- High speed and high precision data acquisition systems
- Audio signal switching and routing
- Automated test equipment (ATE) systems
- Avionics applications
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status using official documentation. Check for discontinuation notices as availability may be limited. Validate package integrity upon receipt. Ensure storage conditions meet specified requirements to maintain reliability.
Selection Notes
Select this part for applications requiring differential signal routing with low leakage and high isolation. Verify that the 380 Ω maximum on-resistance meets system loss requirements. Ensure the 16-lead PDIP package fits the PCB layout constraints. Confirm that the 250 MHz bandwidth supports the highest frequency signals in the design.
Part Context
This component belongs to the DG508B/DG509B series of precision CMOS analog multiplexers. The DG509B specifically provides dual 4:1 differential switching capability. It serves as a successor to older generations like the DG509A, offering improved performance metrics such as lower charge injection and higher voltage ratings while maintaining pin compatibility.
Replacement Considerations
Officially documented superior alternatives include ADG508A, DG508A, HI-508, ADG509A, DG509A, and HI-509. Verify pinout compatibility and electrical parameter alignment before substitution.
