Overview
The DG9422DV-T1-E3 is a single-channel, normally open SPST analog switch manufactured by Vishay Siliconix. It utilizes CMOS technology and operates within a single supply voltage range of 2.7 V to 12 V or dual supplies of ±2.7 V to ±6 V. The device features a maximum on-resistance of 3 Ohms and supports a DC switch current of 50 mA. Key timing parameters include a maximum turn-on time of 45 ns and a maximum turn-off time of 47 ns. It is housed in a TSOP-6 surface-mount package with an operating temperature range from -40°C to +85°C.
Feature Summary
- Single-channel SPST configuration for signal routing
- Low on-resistance for minimal signal attenuation
- Compatible with single and dual power supply systems
Applications
- Data acquisition systems
- Audio and video signal switching
- Communication equipment
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as availability may be restricted. Ensure the specific tape-and-reel packaging matches production requirements before finalizing orders.
Selection Notes
Select this component when a low-cost, single-pole switch with moderate speed is required. Compare on-resistance stability and charge injection against alternatives if precision analog performance is critical. Verify that the TSOP-6 footprint fits the design constraints.
Part Context
This part belongs to the DG942x series of analog switches from Vishay Siliconix. It shares functional similarities with other members like the DG9421 but differs in channel count and specific electrical characteristics. The series is designed for general-purpose signal switching applications requiring compact packaging.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official replacement guides or contact the manufacturer for qualified alternatives.
