Overview
The DG2043DN-T1-E4 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. The device features a maximum on-resistance of 1.5 Ohms and supports a DC switch current of 50 mA. Switching performance includes a maximum turn-on time of 42 ns and a maximum turn-off time of 32 ns. It is housed in a TSSOP-16 surface-mount package and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Quad SPST configuration for independent channel control
- Low on-resistance for minimal signal attenuation
- Fast switching speeds suitable for high-frequency applications
- Single-supply operation compatible with low-voltage logic
Applications
- Signal routing in data acquisition systems
- Audio and video signal switching
- Communication equipment multiplexing
- Test and measurement instrumentation
Procurement Notes
Verify the specific suffix DN against the requested model, as the provided reference data lists DG2043DQ-T1-E3. Confirm package type compatibility and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Ensure the component meets all environmental and electrical specifications required for the target application.
Selection Notes
Select this component when a quad SPST analog switch is required with low on-resistance and fast switching times. Verify that the single-supply voltage range of 1.8 V to 5.5 V aligns with the system power rails. Consider the TSSOP-16 package constraints for PCB layout and thermal management requirements.
Part Context
This part belongs to the DG series of enhanced analog switches from Vishay Siliconix. These devices are designed for general-purpose signal switching applications requiring low distortion and high bandwidth. The series offers various configurations including SPST, SPDT, and multiplexer options in different package styles.
Replacement Considerations
Check for direct pin-compatible substitutes within the DG204x family. Verify if alternative packages such as DQ or DN variants offer identical electrical characteristics. Consult Vishay documentation for recommended alternates if the exact part number is unavailable.
