DG509BEY-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG509BEY-T1-E3 is a dual 4-channel differential analog multiplexer fabricated on an enhanced SG-II CMOS process. It connects one of four differential inputs to a common dual output via a 2-bit binary address (A0, A1). The device features break-before-make switching to prevent crosstalk and includes an enable function for stacking multiple units. It operates with single or dual power supplies ranging from ±5 V to ±20 V, or up to 44 V absolute maximum rating. The component is housed in a 16-lead Narrow SOIC package and supports an extended operating temperature range from -40 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual 4-channel differential configuration with TTL-compatible control inputs
• Break-before-make switching action minimizes momentary crosstalk between channels
• Enhanced SG-II CMOS process reduces charge injection and leakage current
• Extended voltage rating allows operation with supply rails up to 44 V

• Automated test equipment (ATE) systems
• Medical instrumentation

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix T1-E3 confirms the tape-and-reel packaging format and RoHS compliance status required for your assembly line. Confirm that the 16-lead Narrow SOIC footprint matches your PCB design constraints. Ensure the extended temperature grade (-40 °C to +125 °C) aligns with your environmental specifications before finalizing orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a dual differential multiplexer is required rather than a single-ended configuration. Verify that the 380 Ω maximum on-resistance at ±15 V meets your signal integrity requirements. Consider the 250 MHz bandwidth if high-frequency signal fidelity is critical. Ensure the 2-bit address interface fits your digital control logic capabilities.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the Vishay Siliconix DG508B/DG509B family of precision analog multiplexers. The DG509B specifically provides two independent 4:1 multiplexing functions, whereas the DG508B offers a single 8:1 configuration. Both share similar electrical characteristics and package options within the same product series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Official datasheets list ADG508A, DG508A, HI-508, ADG509A, DG509A, and HI-509 as comparable alternatives. Verify pinout compatibility and electrical parameter overlaps before substituting these legacy or competitor parts.
