DG611DY-T1

Overview

The DG611DY-T1 is a high-speed, low-glitch analog switch manufactured by Vishay Siliconix. It features four independently controlled single-pole single-throw (SPST) channels housed 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 4 V to 21 V, with a maximum on-resistance of 45 Ω at room temperature. Key electrical parameters include a charge injection of ±2 pC, an input capacitance of 5 pF, and a quiescent power consumption of 1.2 nW. The component supports logic levels compatible with 5 V CMOS standards.

Feature Summary

• Combines lateral DMOS switching FETs with low-power CMOS control logic for optimized performance
• Minimizes charge injection to reduce offset errors in fast sample-and-hold applications
• Provides glitch-less switching to eliminate halos in video signal routing
• Features an epitaxial layer to prevent latchup during operation

Applications

• Fast sample-and-hold circuits requiring minimal 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

Procurement Notes

Verify the specific suffix 'T1' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the 'D' suffix aligns with the -40 °C to +85 °C operating temperature range specified for this variant. Ensure compatibility with 5 V CMOS logic levels before finalizing procurement specifications.

Selection Notes

Select the DG611DY-T1 when low charge injection and high bandwidth are critical for signal integrity. This part is suitable for applications requiring fast switching speeds without significant transient glitches. Consider the 16-pin narrow SOIC package constraints and verify that the analog signal range fits within the specified supply voltage limits.

Part Context

This component belongs to the DG61x family, which includes the DG611, DG612, and DG613 variants. The DG611 specifically provides four normally open switches that activate with a logic high input. It differs from the DG612, which responds to opposite logic levels, and the DG613, which offers a mix of normally open and normally closed configurations.

Replacement Considerations

Direct replacements within the same family include the DG612DY-T1 for inverted logic requirements and the DG613DY-T1 for mixed SPST/SPDT configurations. Verify pinout compatibility and ensure the substitute maintains the required 12 ns switching speed and 500 MHz bandwidth specifications.
