Overview
The TS3A24159DRCRG4 is a dual single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.65 V to 3.6 V, making it suitable for low-voltage portable applications. The device features a maximum on-resistance of 0.3 ohms and supports a continuous DC current of 100 mA per channel. Key electrical parameters include a maximum propagation delay of 35 ns and an off-isolation characteristic that ensures signal integrity. The component functions as a multiplexer or demultiplexer in data acquisition systems.
Feature Summary
- Ultra-low on-resistance for minimal signal attenuation
- Low power consumption with high off-isolation
- Compatible with digital logic families including CMOS and LVTTL
Applications
- Portable medical equipment such as pulse oximeters
- Audio signal routing in mobile devices
- Data acquisition systems requiring signal multiplexing
Procurement Notes
Verify the specific suffix DRCRG4 against the official Texas Instruments datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the intended PCB footprint and reflow soldering profile. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability before procurement.
Selection Notes
Select this component when a dual SPDT configuration with very low on-resistance is required within a 1.65 V to 3.6 V supply range. Compare against the TS3A24157 if higher on-resistance is acceptable for cost reduction. Verify that the UCSP package dimensions fit the design constraints and that the operating temperature range meets the application environment requirements.
Part Context
This part belongs to the TS3A2415x family of analog switches designed for space-constrained applications. It serves as a low-cost alternative to mechanical relays and other solid-state switches. The device is commonly used in consumer electronics where signal switching speed and power efficiency are critical design factors.
Replacement Considerations
The TS3A24157DGSR is a pin-compatible alternative with a higher on-resistance of 0.65 ohms. Verify that the increased resistance does not impact signal integrity in the specific application circuit before substituting.
