Overview
The TS12A4517DBVR 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 for single supplies or 1 V to 6 V for dual supplies. The device features a maximum on-state 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 and is housed in a compact SOT-23-5 surface-mount package.
Feature Summary
- Low power consumption with a maximum supply current of 70 uA
- Capable of handling high DC switch currents up to 20 mA
- Operates effectively at low supply voltages starting from 2 V
Applications
- Battery-powered portable equipment requiring low voltage operation
- Signal routing in communication systems
- Data acquisition systems
Procurement Notes
Verify the specific ordering suffix DBVR to confirm the SOT-23-5 package and tape-and-reel packaging configuration. Ensure that the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the manufacturer part number with official datasheets to validate electrical characteristics against system design constraints before finalizing procurement orders.
Selection Notes
Select this component when a single-pole single-throw switch is required for signals ranging between 2 V and 12 V. It is suitable for applications prioritizing low quiescent current and moderate on-resistance. Consider alternative packages if higher channel counts or different thermal performance are needed. Verify that the 20 Ohm on-resistance aligns with signal integrity requirements for the intended application bandwidth.
Part Context
This component belongs to the TS12A4517 series of low-voltage analog switches. It shares functional similarities with other devices in the family but differs in package type and specific pinout configurations. The DBVR suffix indicates a specific reel-based packaging format designed for automated surface-mount assembly processes.
Replacement Considerations
The TS12A4516DG4 is a related device offering similar electrical characteristics but utilizes an SOIC-8 package instead of SOT-23-5. Direct pin-to-pin replacement may not be feasible due to the physical footprint difference. Evaluate mechanical constraints and PCB layout compatibility before considering substitution.
