Overview
The TS12A4517DR is a low-voltage, single-channel SPST analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 12 V or dual supplies of ±1 V to ±6 V. The device features a maximum on-resistance of 20 Ohms and supports a DC switch current of 20 mA. Key timing parameters include a maximum turn-on time of 75 ns and a maximum turn-off time of 45 ns. It is housed in an SOIC-8 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Single-pole single-throw (SPST) configuration for signal routing
- Low on-resistance suitable for precision applications
- Compatible with wide single and dual power supply ranges
Applications
- Portable battery-powered equipment
- Automotive electronics
- Industrial process control systems
Procurement Notes
Verify the specific suffix 'DR' indicates tape-and-reel packaging when sourcing components. Confirm that the SOIC-8 package dimensions match the design footprint requirements. Ensure the operating environment stays within the specified -40°C to +85°C temperature limits to maintain performance specifications.
Selection Notes
Select this component for applications requiring a single channel with low on-resistance under low-voltage conditions. Compare against other members of the TS12A4517 family if multiple channels are needed. Verify that the 20 mA switch current capability meets the load requirements of the target circuit design.
Part Context
This part belongs to the TS12A4517 series of low-voltage analog switches. It shares core electrical characteristics with variants such as the TS12A4517D, differing primarily in packaging format. The series is designed for general-purpose signal switching in space-constrained electronic designs.
Replacement Considerations
Check for direct equivalents within the same manufacturer's portfolio. Verify pin compatibility and electrical parameter alignment before substituting with other single-channel SPST switches.
