DG611DY-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG611DY-E3 is a high-speed, low-glitch analog switch manufactured by Vishay Siliconix. It features four single-pole single-throw (SPST) channels in a 16-pin narrow SOIC package. The device utilizes D/CMOS technology to achieve fast switching with a turn-on time of 12 ns and a bandwidth of 500 MHz. It operates on a single supply voltage ranging from 5 V to 21 V, with an on-resistance maximum of 45 Ω at room temperature. Key electrical parameters include a charge injection of ±2 pC, off-isolation of 74 dB at 5 MHz, and quiescent power consumption as low as 1.2 nW.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• High-speed lateral DMOS switches optimized for minimal charge injection and low glitch energy
• Low on-resistance and wide bandwidth ensuring minimal insertion loss
• Compatible with 5 V CMOS logic levels for simple interfacing
• Epitaxial layer integration prevents latchup under stress conditions

Analog Switches, Multiplexers, Demultiplexers Applications

• Fast sample-and-hold circuits requiring low aperture uncertainty
• Pixel-rate video switching for picture-in-picture and title overlays
• GaAs FET drivers for phased array radar systems
• DAC deglitching and synchronous demodulators

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E3' indicates lead-free compliance when sourcing replacements. Confirm the 'DY' designation corresponds to the 16-pin narrow SOIC package required for your PCB footprint. Ensure the component meets the -40 °C to +85 °C operating temperature range specified for this variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG611DY-E3 when low charge injection and high bandwidth are critical for signal integrity. This part responds to opposite logic levels compared to the DG612; verify control logic compatibility before implementation. Consider the DG613 if mixed normally open and normally closed configurations are needed within the same package.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG61x family of high-speed analog switches designed for precision applications. It shares the same physical package and pinout as the DG612 and DG613, differing primarily in internal logic polarity and switch configuration. The DG611 specifically provides four SPST switches that activate with a logic low input.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG612DY-E3: Identical package and speed but activates with logic high. DG613DY-E3: Offers mixed NO/NC configurations in the same package.
