Overview
The DG419LDQ-T1-E3 is a single-channel, single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates within a dual supply voltage range of ±15 V and supports single supplies up to 15 V. The device features a maximum on-resistance of 18.5 ohms, with a maximum turn-on time of 41 ns and a maximum turn-off time of 32 ns. It is housed in an MSOP-8 surface-mount package and functions across an operating temperature range from -40°C to +85°C.
Feature Summary
- Single SPDT configuration for signal routing applications
- Low power consumption with maximum supply current of 1 µA
- High DC switch current capability of 30 mA
- Compatible with single or dual power supply systems
Applications
- Data acquisition systems requiring signal multiplexing
- Instrumentation circuits for channel selection
- Communication equipment signal path switching
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check for end-of-life notifications as availability may be restricted. Ensure packaging format matches design requirements for surface mount assembly processes.
Selection Notes
Select this component when a single SPDT switch with moderate speed and low leakage is required. Compare on-resistance specifications against circuit tolerance limits. Verify that the MSOP-8 package dimensions fit the printed circuit board layout constraints. Ensure supply voltages remain within the specified ±15 V dual or 15 V single limit.
Part Context
This part belongs to the DG series of analog switches from Vishay Siliconix. It shares functional similarities with other DG41x variants but differs in package type and specific electrical tolerances. The suffix indicates tape-and-reel packaging and lead-free composition.
Replacement Considerations
Officially recommended alternatives include the DG419LDY-T1-E3 and DG419LDQ. Verify pin compatibility and electrical parameters before substitution. Cross-reference datasheets for any differences in thermal performance or package footprint.
