DG408AK-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG408AK-E3 is an 8-channel single-ended analog multiplexer manufactured by Vishay Siliconix. It connects one of eight inputs to a common output based on a 3-bit binary address (A0, A1, A2). The device features CMOS logic and supports single supply operation with a maximum rating of 44 V. Key electrical parameters include a maximum on-resistance of 100 Ω, charge injection of 20 pC, and transition times of 160 ns. Supply current is typically 10 µA. It operates within a temperature range of -55°C to +125°C and utilizes a 16-pin DIP package.
