DG507BEQ-T1-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG507BEQ-T1-GE3 is a dual 8-channel differential analog multiplexer manufactured by Vishay Siliconix. It connects one of eight differential inputs to a common dual output using a 3-bit binary address (A0, A1, A2). The device operates with single or dual power supplies ranging from ±5 V to ±20 V, or up to 44 V absolute maximum rating. Key electrical parameters include an on-resistance of 300 Ω at room temperature and 400 Ω across the full range, transition time of 300 ns, and charge injection of 1 pC. It features TTL-compatible control inputs, break-before-make switching, and an enable function for stacking devices.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'EQ' corresponds to the TSSOP-28 package when sourcing replacements. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the supply voltage does not exceed the 44 V absolute maximum rating during operation. Validate that the thermal dissipation requirements are met for the specific PCB layout.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring differential signal routing with minimal glitching. The DG507B variant is distinct from the DG506B, which offers single-ended 16-channel connectivity. Consider the TSSOP-28 package constraints regarding thermal resistance and board space. Verify compatibility with existing logic levels given the TTL-compatible input specifications.

Analog Switches, Multiplexers, Demultiplexers Part Context
