DG2750DN-T1-E4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2750DN-T1-E4 is a dual single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates from a single power supply ranging from 1.6 V to 5.5 V and features a typical on-resistance of 0.45 Ω at room temperature, with a maximum of 1.3 Ω across the full operating temperature range. The device supports negative swing audio signals without requiring coupling capacitors. It includes latch-up protection exceeding 600 mA per JESD78 standards and offers an ESD rating of 8 kV under the Human Body Model. The component is housed in a compact miniQFN-10 package measuring 1.4 mm x 1.8 mm x 0.55 mm.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix '-E4' corresponds to the nickel-palladium-gold termination required for lead-free compliance and JEDEC reflow standards. Confirm that the specific package variant matches the design footprint, as the standard DG2750DN uses a 0.55 mm height while the DG2750DN1 variant utilizes a thinner 0.35 mm ultra-thin profile. Ensure the application environment remains within the specified -40 °C to +85 °C temperature range.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring bi-directional signal routing with minimal distortion. The low on-resistance makes it suitable for maintaining signal integrity in audio paths. Verify that the control logic voltage aligns with the guaranteed 1.4 V high-level input threshold when operating at lower supply voltages. Consider the 4 pC charge injection specification when designing circuits sensitive to transient voltage spikes during switching events.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2750 series of low-voltage analog switches designed for portable electronics. It serves as a direct replacement for legacy SPDT switches in space-constrained designs. The miniQFN-10 package allows for significant board area reduction compared to traditional surface-mount packages. The device integrates robust protection features to withstand electrostatic discharge and latch-up conditions common in consumer hardware.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG2750DN1-T1-GE4 is a confirmed alternative offering the same electrical characteristics but packaged in an ultra-thin UTMQFN-10 form factor with a reduced thickness of 0.35 mm.
