Overview
The DG2042DQ-T1-E3 is a quad single-pole single-throw (SPST) analog switch 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 continuous DC switch current of 50 mA and draws a maximum supply current of 1 uA. 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 suitable for precision signal routing
- Ultra-low power consumption with minimal supply current draw
Applications
- Battery-powered portable instrumentation
- Data acquisition systems requiring low power operation
- Signal multiplexing in communication equipment
Procurement Notes
Verify the specific suffix against official Vishay documentation to confirm tape-and-reel packaging details. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate availability status and lead times prior to procurement planning.
Selection Notes
Select this component when designing circuits that require low-voltage operation below 3.3 V or 5 V rails. The low on-resistance makes it appropriate for applications demanding minimal signal attenuation. Verify that the required switching speed aligns with the specified 42 ns turn-on time constraints of the system architecture.
Part Context
This part belongs to the DG series of CMOS analog switches produced by Vishay Siliconix. The DG2042 variant specifically provides four independent channels in a compact TSSOP-16 footprint. It serves as a modern replacement for legacy discrete switching solutions, offering improved integration and reduced board space requirements for signal path management.
Replacement Considerations
The DG2042DQ-E3 is listed as an alias for this part number. Verify pinout compatibility if substituting with other quad SPST switches from the same family.
