Overview
The TS12A4514DR is a low-voltage, low on-resistance single-pole single-throw (SPST) CMOS analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 12 V and features a maximum on-resistance of 10 Ohms. The device supports a DC switch current of 20 mA and draws a maximum supply current of 200 nA. Key timing specifications 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 operating temperature range from -40°C to +85°C.
Feature Summary
- Provides low on-resistance for efficient signal transmission in low-voltage applications.
- Features ultra-low power consumption with minimal supply current draw.
- Ensures fast switching performance with defined turn-on and turn-off times.
Applications
- Portable battery-powered equipment requiring low power consumption
- Signal routing in communication systems
- Sample-and-hold circuits
Procurement Notes
Verify the component authenticity by checking the manufacturer's marking and datasheet alignment. Confirm the SOIC-8 package type and the DR suffix designation for reel packaging. Ensure the order matches the specific TS12A4514DR part number to avoid confusion with similar series variants. Cross-reference the RoHS compliance status as indicated in official documentation before finalizing procurement.
Selection Notes
Select this component when a single-channel analog switch is required for low-voltage operation between 2 V and 12 V. It is suitable for designs prioritizing low on-resistance and minimal power usage. Consider the SOIC-8 footprint for surface-mount assembly constraints. Verify that the 20 mA switch current capability meets the load requirements of the specific application circuit.
Part Context
This part belongs to the TS12A4514 series of analog switches from Texas Instruments. It is designed for general-purpose signal switching in consumer and industrial electronics. The device complements other components in signal chain designs where low distortion and high bandwidth are not the primary constraints, but rather power efficiency and cost-effectiveness.
Replacement Considerations
Consult the official datasheet for direct pin-to-pin compatible alternatives within the same family or broader product line. Verify electrical parameters such as on-resistance and supply voltage ranges match the original design requirements before substituting.
