DG2520DV-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The Vishay Siliconix DG2520DV-T1-E3 is a single-pole double-throw (SPDT) analog switch operating on a 1.8 V to 5.5 V single supply. It features sub-ohm on-resistance with typical values of 0.4 Ω at 4.5 V and 0.6 Ω at 3 V, alongside excellent matching and flatness. The device incorporates overcurrent protection that activates at a typical threshold of 1.7 A, pulsing the switch off for approximately 1 µs before attempting recovery every 5 ms. It supports full rail signal swing, offers 1.6 V logic compatibility, and provides high bandwidth up to 40 MHz. Packaged in a TSOP-6 surface-mount format, it operates within a temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrated overcurrent protection circuitry that detects short circuits and automatically pulses the switch off to prevent damage.
• Low on-resistance characteristics ensure high linearity and minimal signal distortion across the entire voltage range.
• Compatible with 1.6 V logic levels throughout the full operating supply voltage range.
• Supports full rail-to-rail signal swing without requiring negative supply voltages.

Analog Switches, Multiplexers, Demultiplexers Applications

• USB and UART signal switching
• Audio and video signal routing
• Cellular phone circuitry
• Media players and modems
• Hard drives and PCMCIA interfaces

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and lead-free status. Confirm the active lifecycle status directly with authorized distributors or the manufacturer, as availability may vary by region. Ensure the component meets RoHS compliance requirements for your specific manufacturing process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high linearity are critical for maintaining signal integrity in audio or data paths. The integrated overcurrent protection makes it suitable for applications prone to accidental short circuits. Verify that the required logic input voltage aligns with the 1.6 V compatibility specification and that the power supply range fits within the 1.8 V to 5.5 V limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2520/DG2521 family of sub-ohm, low-voltage SPDT analog switches manufactured using a proprietary sub-micron high-density CMOS process. The DG2520 variant utilizes break-before-make switching, while the DG2521 uses make-before-break. Both share identical electrical specifications and physical packaging but differ in their switching timing characteristics.
