DG2733DN-T1-E4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2733DN-T1-E4 is a low voltage, dual single-pole/double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates on a single supply ranging from 1.65 V to 4.3 V and features a maximum on-resistance of 0.4 Ω at 3.6 V. The device includes an enable pin for logic control and guarantees break-before-make switching. It supports continuous currents up to 250 mA and offers latch-up protection exceeding 300 mA per JESD78 standards. Packaged in a lead-free DFN-10 format with nickel-palladium-gold terminations, it functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix '-E4' to confirm the use of nickel-palladium-gold terminations required for lead-free compliance. Ensure the selected package variant matches the intended PCB footprint, as the DFN-10 package requires specific soldering considerations compared to other available options like MSOP-10.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single-supply operation between 1.65 V and 4.3 V is required. The DG2733 variant specifically provides an enable pin for power management, distinguishing it from the DG2731 and DG2732 models which utilize separate control pins. Verify that the 0.4 Ω on-resistance meets the signal integrity requirements of the target application.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2731/2732/2733 family of low voltage analog switches. While all three share similar electrical characteristics, the DG2733 uniquely incorporates an enable pin for simplified control logic. The 'DN' designation indicates the DFN-10 package, and the '-E4' suffix specifies the lead-free nickel-palladium-gold termination finish.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the DG2733 differ from the DG2731?

The DG2733 includes an enable (EN) pin to activate the device when the logic is high, whereas the DG2731 utilizes two separate control pins with reverse control logic.

What is the maximum continuous current rating?

The maximum continuous current for the NO, NC, or COM terminals is ±250 mA.

Does the device support bidirectional signal flow?

Yes, the switch conducts signals within the power rails equally well in both directions when turned on.
