Vishay DG2523DN-T1-GE4 Analogue SPDT Switch, 4 Dual SPDT, Demultiplexer, Multiplexer, 16-Pin QFN

This analogue SPDT switch provides compact, surface-mounted switching for routing analogue signals in low-voltage systems. Designed as a dual-throw device with two independently controlled paths on each channel, it serves as a small-signal multiplexer/demultiplexer for mixed-signal designs. The component is aimed at applications requiring precise, low-resistance switching across a broad operating-voltage range and standard commercial temperature conditions.

• Low on-resistance 0.65Ω for minimal signal loss
• Operates from 1.8V to 5.5V to support varied supply rails
• Dual SPDT configuration enabling four switching elements
• Surface-mount QFN package for automated assembly
• ESD protection HBM greater than 6 kV to reduce damage risk
• Temperature range -40 to 85 °C for stable performance

• Used for analogue signal selection in instrumentation
• Suitable for multiplexing audio or sensor lines
• Ideal for switching inputs in test and measurement equipment
• Can be used for channel routing in handheld devices
• Used with low-voltage data-acquisition front ends

There are four distinct switching elements providing two SPDT functions per chip.

The device arrives in a 16-pin QFN package requiring a small footprint and solder-pad array for reflow assembly.

It meets a human-body-model threshold exceeding 6 kV, offering enhanced tolerance to common handling discharges.

The switch supports operation across a 1.8V to 5.5V range, accommodating both lower-power and standard logic supplies.
