DESCRIPTION
The DG408 is an 8-channel single-ended analog multiplexer Applications for the DG408/409 include high speed data designed to connect one of eight inputs to a common output acquisition, audio signal switching and routing, ATE systems, as determined by a 3-bit binary address (A0, A1, A2). The and avionics. High performance and low power dissipation DG409 is a dual 4-channel differential analog multiplexer make them ideal for battery operated and remote designed to connect one of four differential inputs to a common instrumentation applications.
dual output as determined by its 2-bit binary address (A0, A1). Break-before-make switching action protects against momentary crosstalk between adjacent channels.
Designed in the 44-V silicon-gate CMOS process, the absolute maximum voltage rating is extended to 44 V.
An on channel conducts current equally well in both directions. Additionally, single supply operation is also allowed. An In the off state each channel blocks voltages up to the power epitaxial layer prevents latchup. supply rails. An enable (EN) function allows the user to reset the multiplexer/demultiplexer to all switches off for stacking several devices. All control inputs, address (Ax) and enable (EN) are TTL compatible over the full specified operating For additional information please see Technical Article TA201 temperature range.

Frequently Asked Questions
What is the difference between the DG408 and DG409 models?
The DG408 is an 8-channel single-ended analog multiplexer, while the DG409 is a dual 4-channel differential one.
Can this device operate using single supply power?
Yes, the unit supports single-supply operation and operates within wide ranges of 5 V to 20 V.
How can I reset all switching channels simultaneously?
Using the enable (EN) function allows the user to reset the multiplexer/demultiplexer so that all switches are placed in the off state.
What is the maximum specified voltage rating for operation?
The absolute maximum voltage rating of the device is extended to 44 V when utilizing the 44-V silicon-gate CMOS process.
