Overview
The TS12A4517D is a single-channel, low-voltage, low on-state resistance SPST analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 12 V for single supplies or 1 V to 6 V for dual supplies. The device features a maximum on-resistance of 20 Ohms and supports a DC switch current of 20 mA. Key timing specifications include a maximum turn-on time of 75 ns and a maximum turn-off time of 45 ns. It functions reliably across an operating temperature range from -40°C to +85°C. The component is housed in an SOIC-8 surface-mount package with a maximum power dissipation of 471 mW and a maximum supply current of 70 uA.
Feature Summary
- Single-pole single-throw (SPST) configuration providing one independent signal path control.
Applications
- Signal routing in portable battery-powered equipment
- Audio and video signal switching applications
- Data acquisition systems requiring low voltage operation
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure that the selected variant matches the required RoHS compliance status and industrial temperature rating. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before finalizing procurement orders.
Selection Notes
Select this component when a single analog channel requires switching under low voltage conditions. The 20 Ohm on-resistance suits applications where moderate signal integrity is acceptable. Verify that the 2 V minimum supply requirement aligns with the system's power rails. Consider the SOIC-8 package dimensions for PCB layout constraints and thermal management requirements during the design phase.
Part Context
This device belongs to the TS12A4517 series of low-voltage analog switches. It shares functional similarities with other members of the family but differs in channel count and specific electrical characteristics. The TS12A4517D represents the single-channel variant designed for cost-sensitive and space-constrained designs requiring basic signal switching capabilities.
Replacement Considerations
The TS12A4516D is a documented alternative within the same product family offering similar SPST functionality and electrical parameters. Verify pin compatibility and package dimensions before substitution. Other series members may offer different channel counts or performance metrics.
