DG642DJ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG642DJ-E3 is a single-pole double-throw (SPDT) video switch integrated circuit manufactured by Vishay / Siliconix. It operates within a supply voltage range of 10 V to 21 V and supports a maximum dual supply voltage of 15 V. The device features a maximum on-resistance of 8 Ohms and a -3 dB bandwidth of 500 MHz. Switching times are specified with a maximum turn-on time of 100 ns and a maximum turn-off time of 60 ns. It is housed in an 8-pin DIP package and functions reliably across an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm compliance with current environmental standards, as the E3 designation typically indicates RoHS compliance. Confirm package dimensions and pinout compatibility during integration planning. Check manufacturer lifecycle status for long-term availability assurance before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single SPDT configuration with high bandwidth is required. Ensure the system supply voltage remains within the 10 V to 21 V range. Compare on-resistance and switching speed requirements against alternative models if lower power consumption or different channel counts are needed. Verify thermal management capabilities for the DIP-8 package under expected load conditions.

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 DG643 but differs in channel count and configuration. The series is characterized by CMOS technology optimized for video frequency applications. It serves as a discrete solution for analog signal path control in industrial and consumer electronics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public sources indicate DG642DJ-E3 is obsolete. Recommended alternatives include the DG642DY-E3 (SOIC-16 package) or DG643DJ-E3 (dual SPDT). Verify pinout compatibility and package footprint changes when substituting these parts.
