Overview
The TS12A4514DBVR is a single-channel, low-voltage, low on-resistance SPST analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features a maximum on-resistance of 8 Ohms. The device supports a continuous DC switch current of 100 mA with a maximum power dissipation of 360 mW. Switching performance includes a maximum turn-on time of 17 ns and a maximum turn-off time of 14 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
- Single-pole single-throw (SPST) configuration for signal routing
- Low on-resistance of 8 Ohms for minimal signal loss
- High continuous DC switch current capability of 100 mA
- Ultra-low quiescent current consumption
Applications
- Portable battery-powered equipment
- Audio and video signal switching
- Communication equipment signal paths
- Instrumentation and measurement systems
Procurement Notes
Verify the specific suffix 'DBVR' to confirm the SOT-23-5 package type and tape-and-reel shipping format. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number against official datasheets to validate electrical specifications before integration into production designs.
Selection Notes
Select this component when a single analog channel requires low on-resistance and high current handling within a small footprint. It is suitable for applications demanding low power consumption and operation from a single 2 V to 5.5 V supply. Consider alternative packages if larger thermal dissipation or different pin counts are required for the design.
Part Context
This part belongs to the TSxA45xx series of low-voltage analog switches from Texas Instruments. These devices are designed for portable applications where space and power efficiency are critical constraints. The series offers various configurations including SPST, SPDT, and dual-channel options to suit different signal routing needs.
Replacement Considerations
Compatible substitutes include the TS5A4594DR and TS5A4594DGR, which share similar electrical characteristics and SPST functionality. Verify pin compatibility and package dimensions before substitution to ensure mechanical fit within the existing PCB layout.
