Overview
The TS12A44513DR is a low on-state resistance quad SPST CMOS analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 12 V and supports a single-supply configuration. The device features four independent channels, each with a maximum on-resistance of 10 Ohms. Electrical performance includes a maximum operating frequency of 75 ns for turn-on time and 45 ns for turn-off time. Power consumption is limited to a maximum supply current of 200 nA, with a power dissipation rating of 471 mW. The component functions reliably across an extended temperature range from -40°C to +85°C.
Feature Summary
- Quad SPST CMOS analog switch architecture providing four independent signal paths
- Low on-state resistance characteristic ensuring minimal signal attenuation
- CMOS technology enabling ultra-low quiescent current operation
- Rail-to-rail switching capability compatible with various logic levels
Applications
- Portable battery-powered equipment requiring low power consumption
- Audio and video signal routing in consumer electronics
- Communication instruments and test equipment signal switching
- Industrial process control systems for sensor multiplexing
Procurement Notes
Verify the specific ordering suffix DR indicates tape and reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the supplier provides valid traceability records matching the Texas Instruments part number TS12A44513DR to guarantee authenticity and quality assurance standards.
Selection Notes
Select this component when designing circuits requiring multiple independent single-pole switches with low insertion loss. The wide supply voltage range accommodates both 3.3 V and 5 V logic systems. Consider the SOIC-8 package dimensions for PCB layout constraints. Evaluate thermal dissipation requirements if operating near maximum power limits under continuous load conditions.
Part Context
This device belongs to the TS12A451x family of low-voltage analog switches. It shares functional similarities with other members like the TS12A4514 but differs in channel count and pinout configuration. The TS12A44513 specifically integrates four channels in a compact surface-mount package, distinguishing it from dual-channel variants within the same product line.
Replacement Considerations
Direct substitutes include the TS12A44513PWR for TSSOP-14 packaging options. Verify pin compatibility and electrical specifications against the original design requirements before implementing any alternative packages or cross-brand equivalents.
