Vishay DG1409EEN-T1-GE4 Analogue Switch, 2 CMOS Dual 4:1, Multiplexer, 16-Pin QFN

This analogue switch is a dual 4:1 multiplexer in a compact QFN package designed for signal routing in mixed-signal systems. It operates as a CMOS output device and is suited to surface-mount assemblies where multiple signal channels must be selected and directed with minimal external circuitry. The device supports operation across a wide supply range and is intended for applications that demand robust on-resistance and temperature endurance without occupying through-hole space.

• Low on-state resistance of 14Ω improves signal integrity and reduces loss
• Wide supply range 4.5-24V enables use with varied voltage domains
• Operates from -40°C to 125°C and supports harsh thermal environments
• Dual 4:1 configuration simplifies routing of multiple inputs
• 16-pin QFN surface-mount package reduces board footprint and parasitics

• Suitable for multiplexing audio and analogue sensor signals
• Ideal for test-and-measurement channel selection modules
• Used for signal routing in industrial control electronics
• Can be used for switching between ADC input sources

The QFN layout offers a low-profile thermal path to the PCB, enhancing heat transfer for high-temperature operation.

There are two independent multiplexer elements on the chip, each providing four selectable analogue inputs.

It uses CMOS logic levels for control, permitting straightforward interfacing with common digital controllers.

It is intended for surface-mount assembly
