DG642DY-T1-E3

Overview

The DG642DY-T1-E3 is a single-pole double-throw (SPDT) video switch integrated circuit manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 10 V to 21 V, with a typical operating voltage of 15 V. The device features a maximum on-resistance of 8 Ohms and supports a bandwidth of 500 MHz. Switching performance includes a maximum turn-on time of 100 ns and a maximum turn-off time of 60 ns. Typical off-isolation is rated at -63 dB. Power dissipation is limited to 300 mW. The component functions within an ambient temperature range of -40°C to +85°C and is housed in an SOIC-8 surface-mount package.

Feature Summary

Single SPDT configuration for signal routing applications
High bandwidth capability suitable for video signal transmission
Low on-resistance for minimal signal attenuation
Fast switching times for dynamic signal control

Applications

Video signal switching and routing
Test and measurement equipment signal paths
Data acquisition systems requiring analog switching

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status via official documentation before integration. Check for end-of-life notifications as the product lifecycle status may affect long-term supply continuity. Ensure packaging specifications match production requirements.

Selection Notes

Select this component when a single-channel SPDT switch with high bandwidth is required. Verify that the 8 Ohm on-resistance meets system loss budgets. Confirm that the 10 V to 21 V supply range aligns with available power rails. Consider the SOIC-8 package dimensions for PCB layout compatibility.

Part Context

This part belongs to the DG64x series of video switches from Vishay Siliconix. It shares functional similarities with other devices in the family but offers specific electrical characteristics tailored for video applications. The suffix T1 indicates tape-and-reel packaging, while E3 denotes lead-free composition.
