DG641DJ

Overview

The DG641DJ is a monolithic video switch manufactured by Vishay Siliconix, featuring four single-pole single-throw (SPST) analog switches in a 16-pin plastic dual-in-line package. It operates within a temperature range of -40 °C to +85 °C and supports supply voltages up to 21 V between V+ and V-. The device provides a typical bandwidth of 500 MHz into a 50 Ω load, with a maximum on-resistance of 15 Ω at room temperature and 20 Ω across the full temperature range. Switching times are specified with a maximum turn-on time of 70 ns and a maximum turn-off time of 50 ns under standard test conditions.

Feature Summary

TTL logic compatible input control for simplified interfacing
High bandwidth performance suitable for wideband signal switching
Low insertion loss and minimal non-linear distortion
Bidirectional signal conduction capability

Applications

RF and video switching systems
RGB signal routing
Programmable filter configurations
Radar and FLIR systems
Satellite receivers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package type and environmental compliance standards. Review the latest datasheet revision for any updates to absolute maximum ratings or thermal derating curves before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits requiring multiple independent SPST analog switches with high frequency response. Ensure the application voltage does not exceed the 21 V limit between supply rails. Consider the 16-pin DIP footprint constraints during PCB layout. Verify that the TTL-compatible logic levels align with the system's control interface requirements.

Part Context

This part belongs to the DG641/DG642/DG643 family of low on-resistance wideband video switches. While the DG642 offers a single SPDT configuration and the DG643 provides dual SPDT switches, the DG641 specifically integrates four independent SPST channels. All variants share the same D/CMOS process technology and similar electrical characteristics regarding bandwidth and switching speed.
