Overview
The DG417LAK is a single-channel, single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It operates within a supply voltage range of ±3V to ±15V for dual supplies or 6V to 30V for single supplies. The device features a maximum on-resistance of 20 ohms and a typical on-resistance flatness of 0.1 ohm. Electrical specifications include a maximum turn-on time of 89 ns and a maximum turn-off time of 80 ns. It supports a continuous DC switch current of 30 mA and has a maximum power dissipation of 400 mW. The component is housed in a 16-pin CERDIP package and functions reliably across an operating temperature range of -55°C to +125°C.
Feature Summary
- High-speed switching capability with defined turn-on and turn-off times suitable for signal routing applications.
- Low on-resistance with minimal flatness ensures consistent signal transmission across the operating range.
- Wide dual and single supply voltage operation allows flexibility in various circuit power architectures.
- Extended industrial temperature rating supports reliable performance in harsh environmental conditions.
Applications
- Signal multiplexing and demultiplexing in data acquisition systems
- Audio and video signal path switching
- Instrumentation front-end signal conditioning
Procurement Notes
Verify component authenticity through authorized distributors due to potential availability constraints. Confirm RoHS compliance status as historical variants may differ. Check for obsolescence notices from Vishay Semiconductors prior to finalizing procurement plans. Ensure packaging integrity matches design requirements for surface mount or through-hole assembly processes.
Selection Notes
Select this component when a single SPST configuration is required with high voltage tolerance. Compare on-resistance values against load requirements to ensure acceptable voltage drop. Verify that the 16-pin CERDIP package fits the available board space. Consider thermal management capabilities given the 400 mW power dissipation limit at elevated temperatures.
Part Context
The DG417LAK belongs to the DG41x series of precision analog switches from Vishay Siliconix. This family includes quad configurations such as the DG411 and DG412, offering multiple channels in larger packages. The L suffix typically denotes specific speed or resistance characteristics within the broader DG41x lineup, distinguishing it from standard or low-power variants.
Replacement Considerations
Direct pin-compatible replacements include other Vishay DG41x series devices like the DG411LDY or DG412LDY if channel count adjustments are acceptable. Cross-reference with generic CMOS analog switches ensuring matching voltage ratings and package dimensions. Verify electrical parameters closely match original specifications to maintain circuit performance.
