Overview
The DG187AP/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 a temperature range of -55°C to +125°C and features a 14-pin sidebrazed package. Key electrical parameters include a maximum drain-source on-resistance of 60 ohms at room temperature and 150 ohms across the full temperature range. Leakage currents are minimized to less than 100 nA under specified conditions.
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.
- Offers fault protection capabilities with the ability to block up to 20 V peak-to-peak in the off state.
Applications
- Audio signal switching
- Video signal routing
- Data acquisition systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm military qualification status via JAN38510 documentation. Ensure proper handling procedures are followed due to the ceramic package construction. Validate supply voltage configurations against datasheet limits before integration into final designs.
Selection Notes
Select this component when a specific 30-ohm nominal on-resistance is required for SPDT switching applications. Compare against DG186AA/883 for lower resistance needs or DG188AP/883 for higher current tolerance. Ensure the 14-pin sidebrazed package format aligns with the target PCB layout requirements.
Part Context
This part belongs to the DG186/187/188 series of high-speed drivers with SPDT JFET switches. The 'P' suffix indicates the 14-pin flat pack or sidebrazed variant, while '/883' denotes military-grade screening standards. It serves as a specialized alternative to standard CMOS analog switches requiring superior linearity.
Replacement Considerations
JM38510/11105BCA is the confirmed military specification equivalent part number for the DG187AP/883. Verify pinout compatibility and thermal dissipation characteristics when substituting with other SPDT JFET switches from different manufacturers.
