DG187AA/883

Overview

The DG187AA/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 10-pin metal can package. Key electrical parameters include a maximum drain-source on-resistance of 60 ohms, a saturation drain current of 300 mA, and a logic supply current of 3.2 mA.

Feature Summary

Features break-before-make switching action to eliminate inadvertent channel shorting and reduce crosstalk.
Provides low leakage current for high precision signal handling.
Offers fault protection capabilities and high bandwidth performance.
Designed for applications requiring flat JFET on-resistance across the full analog voltage range.

Applications

Audio switching
Video switching
Data acquisition systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the part number matches the specific military-grade designation and packaging requirements. Review the datasheet for any process option updates or environmental compliance documentation prior to procurement.

Selection Notes

Select this component when a SPDT configuration with low distortion and constant on-resistance is required. Ensure the application supports the specified dual power supply voltages and TTL-compatible logic levels. Consider the thermal dissipation limits associated with the 10-pin metal can package during circuit design.

Part Context

This component belongs to the DG186/187/188 series of high-speed drivers with SPDT JFET switches. The primary distinction between these variants lies in their on-resistance values, with the DG187 offering a moderate resistance profile compared to the lower resistance DG186 and higher resistance DG188.

FAQ

What is the maximum saturation drain current for the DG187?

The maximum saturation drain current (IDSS) is 300 mA with a 2 ms pulse duration.

How does the DG187 prevent signal interference between channels?

It employs a break-before-make switching action via its internal bipolar driver, which prevents inadvertent shorting between channels and reduces crosstalk.
