DG186AA/883

Analog Switches, Multiplexers, Demultiplexers Overview

The DG186AA/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 features break-before-make switching action to eliminate inadvertent shorting between channels. Key electrical parameters include a maximum drain-source on-resistance of 10 ohms, an analog signal range up to 15 V, and low leakage current below 2 nA in the on state. It operates within a temperature range of -55 °C to +125 °C and is housed in a 10-pin metal can package.
