DG183BP

Analog Switches, Multiplexers, Demultiplexers Overview

The DG183BP is a precision dual double-pole, single-throw (DPST) analog switch manufactured by Vishay Siliconix. It utilizes four 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 -25°C to +85°C and is housed in a 16-pin sidebraze package. Key electrical parameters include a maximum drain-source on-resistance of 10 ohms, a source off leakage current of 10 nA at room temperature, and a positive supply current of 1.5 mA.
