DG506BEW-T1-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG506BEW-T1-GE3 is a precision 16-channel single-ended CMOS analog multiplexer manufactured by Vishay Siliconix. It connects one of sixteen inputs to a common output via a 4-bit binary address (A0-A3). The device operates with single or dual power supplies, supporting voltage ranges from ±5 V to ±20 V or up to 44 V absolute maximum rating. Key electrical parameters include a maximum on-resistance of 300 Ω at room temperature, 114 MHz bandwidth, and -85 dB off-isolation. It features break-before-make switching, TTL-compatible logic inputs, and an enable function for stacking. Operating temperature range is -40 °C to +125 °C in a 28-pin SOIC package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Ultra-low charge injection and channel capacitance for superior switching performance
• Break-before-make switching action prevents momentary crosstalk between adjacent channels
• TTL-compatible control inputs over the full specified operating temperature range
• Extended absolute maximum voltage rating of 44 V with epitaxial layer latch-up prevention

Analog Switches, Multiplexers, Demultiplexers Applications

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

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EW' confirms the 28-pin Wide Body SOIC package variant. Confirm RoHS compliance status as GE3 indicates lead-free and halogen-free construction. Check for any recent product discontinuation notifications or lifecycle changes directly from Vishay Siliconix documentation before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single-ended 16:1 multiplexing configuration is required. Ensure the application supports the 300 Ω maximum on-resistance and 114 MHz bandwidth limits. Verify that the system power supply fits within the ±5 V to ±20 V operational range or does not exceed the 44 V absolute maximum rating. Consider the DG507B if differential dual 8:1 multiplexing is needed instead.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG506B/DG507B series, which are enhanced versions fabricated on an SG-II CMOS process. This technology reduces charge injection, lowers leakage, and minimizes parasitic capacitance compared to earlier generations. The series serves as a superior alternative to legacy parts like the ADG506A and HI-506, offering improved ruggedness and wide supply ranges.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitutes listed by distributors include the DG406CWI+ from Analog Devices/Maxim Integrated. Verify pinout compatibility and electrical parameter alignment with the original datasheet specifications before substitution.
