DG642DY-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG642DY-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. It provides typical off-isolation of -63 dB and dissipates up to 300 mW of power. The component is housed in an SOIC-8 surface-mount package and functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited distribution channels. Confirm RoHS compliance documentation matches specific manufacturing dates. Ensure the SOIC-8 package variant aligns with existing PCB footprint constraints before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single SPDT configuration with high bandwidth is required. Compare on-resistance and switching speeds against alternative video switches if signal integrity at frequencies near 500 MHz is critical. Verify that the single-supply voltage range meets the system's power architecture without requiring dual rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG64x series of video switches from Vishay Siliconix. It shares functional similarities with other members like the DG642DJ-E3 but differs in packaging technology. The series is designed for applications demanding fast switching and low distortion in analog signal paths.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG642DJ-E3 serves as a direct functional alternative offering identical electrical specifications but utilizes a DIP-8 through-hole package instead of surface mount. Verify pin compatibility and thermal dissipation differences when substituting packages.
