DG509ACWE

Overview

The DG509ACWE is a monolithic CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It functions as a differential 4-channel (2-of-8) mux, switching one of four differential inputs to a common differential output based on two binary address lines and an enable input. The device operates from dual supplies ranging from ±4.5V to ±18V. Key electrical characteristics include a drain-source on-resistance of 300Ω maximum at ±15V supplies, source off-leakage current of 5nA maximum, and drain off-leakage current of 5nA maximum. Switching performance features a transition time of 1.0µs maximum and an enable turn-on time of 1.5µs maximum. The component is housed in a 16-Wide SOIC package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

Monolithic low-power CMOS design with latchup-proof construction
Guaranteed break-before-make switching for signal integrity
TTL and CMOS compatible logic and enable inputs
Symmetrical, bidirectional operation across the full supply range

Applications

Data-acquisition systems
Signal routing
Control systems
Data logging systems
Aircraft heads-up displays

Procurement Notes

Verify the specific ordering suffix 'CWE' corresponds to the Wide SOIC package and the 0°C to +70°C industrial temperature grade. Confirm that the manufacturer designation matches the intended supply chain requirements, as this part may be sourced through Analog Devices or Maxim Integrated depending on inventory status. Ensure compatibility with existing board layouts for the 16-pin wide surface-mount footprint.

Selection Notes

Select the DG509ACWE when a differential multiplexing solution is required for signals within a ±15V range. This part is suitable for applications needing guaranteed break-before-make timing and robust latchup protection. Consider alternative packages such as the ADJ or AEWE variants if extended temperature ranges beyond the standard industrial limits are necessary for the deployment environment.

Part Context

The DG509ACWE belongs to the DG508A/DG509A family of monolithic CMOS analog multiplexers. While the DG508A provides an 8-channel single-ended configuration, the DG509A specifically addresses differential signal paths with four channels. These devices serve as plug-in upgrades for industry-standard predecessors, offering improved on-resistance, faster switching times, and lower leakage currents compared to older generations.
