DG2733DQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2733DQ-T1-E3 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 utilizes an active-high enable pin for control logic compatibility with 1.6-V systems. Packaged in a 10-pin MSOP, it supports continuous currents up to 250 mA and includes greater than 300 mA latch-up protection per JESD78 standards.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix E3 indicates matte tin terminations compliant with RoHS standards. Confirm the DQ package designation corresponds to the MSOP-10 form factor. Ensure the T1 tape and reel configuration matches the required manufacturing assembly process. Cross-reference the datasheet revision date against current production requirements.

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 is appropriate when an active-high enable pin is preferred over separate control inputs. Verify that the 0.4 Ω on-resistance meets the signal integrity requirements for the target application bandwidth.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2731/2732/2733 family of low voltage analog switches. While sharing identical electrical characteristics and physical packages, the DG2733 distinguishes itself through its dedicated enable pin architecture. This contrasts with the DG2731 and DG2732, which utilize separate control pins with reverse logic functionality.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the DG2733 control logic differ from the DG2731?

The DG2733 uses a single EN pin that enables the device when the logic is high. In contrast, the DG2731 utilizes two separate control pins with reverse control logic.

What is the maximum continuous current rating for the switch terminals?

The maximum continuous current for any terminal except NO, NC, or COM is 30 mA. For the NO, NC, or COM terminals, the limit is ±250 mA.

Does the device support bidirectional signal conduction?

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