DG2043DQ-T1-E3

Overview

The DG2043DQ-T1-E3 is a quad single-pole single-throw (SPST) analog switch IC manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 1.8 V to 5.5 V and features a maximum on-resistance of 1.5 Ohms. The device supports a maximum DC switch current of 50 mA with a maximum power dissipation of 450 mW. Switching performance includes a maximum turn-on time of 42 ns and a maximum turn-off time of 32 ns. It functions within an operating temperature range of -40°C to +85°C and is housed in a 16-pin TSSOP surface-mount package.

Feature Summary

Low on-resistance for minimal signal attenuation
Compatible with low-voltage digital logic interfaces
High-speed switching capability for data acquisition systems

Applications

Portable battery-powered instrumentation
Data acquisition signal routing
Communication equipment signal switching

Procurement Notes

Verify the specific suffix E3 confirms RoHS compliance and halogen-free status as per manufacturer documentation. Confirm the TSSOP-16 package dimensions match the target PCB footprint. Ensure the 1.8 V minimum supply voltage aligns with the system's power rails. Check for any recent Product Change Notifications that may affect pinout or electrical characteristics.

Selection Notes

Select this component when low on-resistance is critical for signal integrity in low-voltage applications. The 1.5 Ohm resistance is significantly lower than standard CMOS switches, reducing voltage drop across the channel. Verify that the 50 mA current limit meets the load requirements. Consider the 42 ns switching speed against the system's timing constraints.

Part Context

This part belongs to the DG series of analog switches from Vishay Siliconix. It is functionally related to other devices in the family but distinguished by its specific low on-resistance and low-voltage operation capabilities. The DQ suffix indicates the 16-lead TSSOP package configuration.
