DG509BEQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG509BEQ-T1-E3 is a dual 4-channel differential analog multiplexer from Vishay Siliconix, 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 operates with single or dual power supplies ranging from ±5 V to ±20 V, supporting up to 44 V maximum ratings. Key electrical parameters include a maximum on-resistance of 380 Ω, a -3 dB bandwidth of 250 MHz, and typical off-isolation of -81 dB at 1 MHz. It features break-before-make switching, TTL-compatible control inputs, and an extended operating temperature range from -40 °C to +125 °C in a 16-lead TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature rating. Ensure that any alternative part numbers are cross-referenced with official substitution lists. Confirm RoHS compliance status through the latest product compliance declarations provided by Vishay Semiconductors before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring differential signal routing with low crosstalk. Verify that the supply voltage range accommodates the system's analog signal swing. Check that the TSSOP-16 package dimensions fit the PCB layout constraints. Ensure the thermal dissipation requirements are met within the specified operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG508B/DG509B family of precision CMOS analog multiplexers. The DG509B specifically provides dual 4-channel functionality, contrasting with the DG508B's single 8-channel design. Both share similar fabrication processes and performance characteristics, offering improved specifications over legacy versions like the DG508/DG509.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Officially listed superior alternatives include ADG508A, DG508A, HI-508, ADG509A, DG509A, and HI-509. Verify pin compatibility and electrical parameter alignment when substituting these parts.
