DG428DN

Analog Switches, Multiplexers, Demultiplexers Overview

The DG428DN is an 8-channel multiplexer switch IC manufactured by Vishay Siliconix, housed in a 20-PLCC surface-mount package. It operates with a single supply voltage up to 12 V or dual supplies of ±15 V. The device features a maximum on-resistance of 100 Ohms and supports channel-to-channel matching of 5 Ohms. Switching times are limited to 150 ns for both turn-on and turn-off periods, with a propagation delay of 250 ns. Power dissipation reaches 800 mW, while leakage current remains below 500 pA. The component functions within a temperature range of -40°C to +85°C.
