Overview
The DG2042DN-T1-E4 is a single-channel SP3T analog switch IC manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 1.6 V to 5.5 V and is housed in an 8-lead QFN package. The device features a maximum on-resistance of 1.1 Ohms, with a typical power dissipation of 190 mW. Switching performance includes a maximum turn-on time of 75 ns and a maximum turn-off time of 60 ns. It supports a DC switch current of 300 mA and maintains a maximum supply current of 1 uA. The component functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Configured as a single-pole triple-throw (SP3T) switch for signal routing applications
- Low on-resistance characteristic suitable for precision analog signal paths
- Operates on low-voltage single-supply configurations
Applications
- Portable battery-powered instrumentation
- Automotive sensor signal conditioning
- Data acquisition systems requiring single-channel multiplexing
Procurement Notes
Verify the specific suffix 'E4' against the manufacturer's latest documentation to confirm RoHS compliance status and material declarations. Confirm availability through authorized distributors, as standard packaging quantities may vary. Ensure the QFN-8L footprint matches the target PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when a single SP3T configuration is required within a compact QFN-8L footprint. Verify that the 1.1 Ohm on-resistance meets the system's signal integrity requirements. Ensure the 1.6 V minimum supply voltage aligns with the available power rails in the design.
Part Context
This part belongs to the DG series of enhanced analog switches from Vishay Siliconix. These devices are designed for high-performance switching applications requiring low distortion and fast switching speeds. The DG2042 variant specifically provides a single SP3T topology, distinguishing it from dual or quad channel counterparts in the same family.
Replacement Considerations
Check for direct pin-compatible replacements within the DG20xx series. Verify if alternative packages such as MSOP or TSSOP are available for the same electrical specifications if board space constraints change.
