DG507BEQ-T1-GE3

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.

Feature Summary

• Dual 8-channel differential configuration with 3-bit address selection
• Ultra-low switch charge injection and low channel capacitance
• Break-before-make switching action prevents momentary crosstalk
• TTL-compatible control inputs over extended temperature range

Applications

• High speed and high precision data acquisition systems
• Audio signal switching and routing
• Automated test equipment (ATE) systems
• Avionics applications

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.

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.

Part Context

This part belongs to the DG506B/DG507B series, fabricated on an enhanced SG-II CMOS process. It serves as a superior alternative to legacy parts like the ADG507A and HI-507. The series is designed for improved performance in reduced charge injection and minimized parasitic capacitance compared to earlier generations.

Replacement Considerations

Publicly confirmed substitutes include ADG507A and HI-507. Verify pinout compatibility and electrical parameter alignment before substitution.
