DG408DJ

The DG408DJ from Siliconix is a high-performance, 8-channel single-ended analog multiplexer. It is designed to connect one of eight inputs to a common output, controlled by a 3-bit binary address. This device offers a low on-resistance of 100 Ω, low charge injection of 20 pC, and a fast transition time of 160 ns, making it suitable for applications requiring high data throughput and reduced switching errors.

The DG408DJ operates with single or dual supply voltages, ranging from +5 V to +36 V for single supply and ±5 V to ±20 V for dual supplies, with an absolute maximum rating of 44 V. Its control inputs, including address and enable, are TTL compatible. The multiplexer also features a break-before-make switching action to prevent momentary crosstalk between adjacent channels. An enable function allows all switches to be turned off, facilitating the stacking of multiple devices.

This analog multiplexer is ideal for applications such as high-speed data acquisition systems, audio signal switching and routing, and automated test equipment (ATE) systems. Its low power consumption of 10 µA makes it suitable for battery-operated and remote instrumentation applications. The DG408DJ is available in a 16-DIP package and is designed for through-hole mounting.
