DESCRIPTION
The DG189/190/191 are precision dual single-pole, double-throw (SPDT) analog switches designed to provide accurate switching of video and audio signals. This series is ideally suited for applications requiring a constant on-resistance over the entire analog range. To achieve fast and accurate switch performance, each device prises four n-channel JFET transistors and a TTL patible bipolar driver. The driver is designed to achieve break-before-make switching action, eliminating the inadvertent shorting between channels and the crosstalk which would result. In the on state, each switch conducts current equally well in either direction. In the off...
