DG188AA

Analog Switches, Multiplexers, Demultiplexers Overview

The DG188AA is a high-speed driver featuring a single-pole double-throw (SPDT) JFET switch, manufactured by Intersil Corporation and distributed by Rochester Electronics. It utilizes a P-channel JFET architecture to provide low on-resistance and fast switching capabilities. The device is housed in a hermetic ceramic dual-in-line package, specifically designed for military and aerospace applications requiring high reliability. Key electrical characteristics include a supply voltage range of ±5V to ±18V, an on-resistance of typically 20 ohms, and a breakdown voltage of 30V. The component operates within a temperature range of -55°C to +125°C, ensuring stability in extreme environments.
