DG641DY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG641DY is a monolithic video switch IC manufactured by Vishay Siliconix, housed in a 16-pin Narrow SOIC package. It features four independent SPST analog switches built on D/CMOS technology. The device supports a maximum supply voltage of 21 V and operates within a temperature range of -40 °C to +85 °C. Key electrical parameters include a typical bandwidth of 500 MHz, an on-resistance (RDS(on)) of 15 Ω at room temperature, and a turn-on time of 50 ns. It provides high off-isolation of -60 dB and low crosstalk of -87 dB at 5 MHz.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• High bandwidth performance suitable for wideband analog signals
• Low insertion loss and negligible non-linearity distortion

Analog Switches, Multiplexers, Demultiplexers Applications

• RF and video switching systems
• RGB signal routing and multiplexing
• Programmable filter configurations
• Radar and FLIR system signal paths

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'DY' confirms the 16-pin Narrow SOIC package format. Confirm RoHS compliance status as required by project specifications. Ensure the ordering part number matches the exact manufacturer designation to avoid pinout or functional discrepancies during component sourcing.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required for high-frequency signal routing. Verify that the 15 Ω on-resistance meets the signal integrity requirements of the application. Consider the single-supply capability if negative voltage rails are unavailable in the design architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the DG64x series alongside the DG642 and DG643 variants. While the DG642 offers a single SPDT configuration and the DG643 provides dual SPDT switches, the DG641 specifically delivers four independent SPST channels. All three share identical packaging options and core D/CMOS process characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public documentation lists the DG641DJ as the Plastic DIP equivalent. No other direct cross-model substitutes are confirmed in the provided datasheet.
