DG186AP/883

Analog Switches, Multiplexers, Demultiplexers Overview

The DG186AP/883 is a precision single-pole, double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It utilizes n-channel JFET transistors and a TTL-compatible bipolar driver to provide accurate switching of video and audio signals with constant on-resistance over the entire analog range. The device operates within an extended temperature range of -55°C to +125°C and is housed in a 14-pin sidebraze package. Key electrical parameters include a typical drain-source on-resistance of 10 ohms at room temperature, rising to a maximum of 20 ohms across the full temperature range. Leakage currents are specified at less than 2 nA under standard conditions.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Features break-before-make switching action to eliminate inadvertent channel shorting and reduce crosstalk.
• Provides low distortion and high precision suitable for demanding signal routing applications.
• Incorporates fault protection capabilities allowing the switches to block up to 20 V peak-to-peak in the off condition.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized channels due to military specifications. Confirm package integrity as the sidebraze variant requires specific handling. Check datasheet revisions for updated testing limits. Ensure supply chain compliance with relevant defense standards. Validate lot traceability before integration into critical assemblies.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this model when precise constant on-resistance is required across wide voltage swings. Compare against DG187 and DG188 variants based on specific resistance thresholds. Verify power dissipation requirements against the 825 mW limit for the sidebraze package. Ensure logic levels match the TTL-compatible input requirements for reliable control.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG186/187/188 series of high-speed drivers with SPDT JFET switches. The suffix AP/883 designates the specific 14-pin sidebraze package configuration operating within the -55°C to +125°C temperature range. This distinguishes it from metal can or flat pack alternatives within the same functional family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include DG187AP/883 and DG188AP/883, which share identical pinouts and packages but offer different on-resistance values of 30 ohms and 75 ohms respectively. Cross-referencing with JAN38510 military specifications is recommended for equivalent sourcing.
