Overview
The TS12A12511DCNR is a single-channel SPDT analog switch manufactured by Texas Instruments, housed in an SC-70-5 surface-mount package. It operates with a supply voltage range of ±6 V or +12 V and features a low on-resistance (rON) of 5 ohms. The device supports bidirectional signal switching with a continuous current rating of 20 mA. Key electrical parameters include a maximum on-resistance variation of 0.3 ohms, ensuring consistent signal integrity across the operating range.
Feature Summary
- Single-pole double-throw (SPDT) configuration for signal routing
- Low on-resistance for minimal signal attenuation
- Bidirectional switching capability
- Compact SC-70-5 footprint for space-constrained designs
Applications
- Signal multiplexing and demultiplexing
- Audio and video signal path switching
- Data acquisition systems
- Communication equipment I/O selection
Procurement Notes
Verify the specific suffix DCNR to confirm the SC-70-5 package and reel packaging format. Ensure compatibility with standard reflow soldering profiles for small outline packages. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated assemblies.
Selection Notes
Select this component when a single SPDT switch with low on-resistance is required in a minimal footprint. Compare against alternatives like TS5A3154 if lower on-resistance is critical, or TS12A4514DR for SPST applications. Evaluate power supply constraints as the device supports dual supplies up to ±6 V or a single +12 V source.
Part Context
Part of the TS12A series of low-voltage analog switches designed for portable and battery-operated applications. The series offers various configurations including SPST and SPDT options in compact packages such as SC-70 and SOT-23, targeting consumer electronics and industrial control markets.
Replacement Considerations
Direct pin-compatible substitutes may include other TI SPDT switches in SC-70-5 packages. Verify on-resistance and voltage ratings against similar parts from Analog Devices or Protek Devices if sourcing from alternative suppliers.
