Overview
The TS12A44514DR is a quad single-pole single-throw (SPST) analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2 V to 12 V. The device features a maximum on-state resistance of 10 Ohms and supports a maximum switching current of 35 mA. Key timing parameters include a maximum turn-on time of 75 ns and a maximum turn-off time of 45 ns. It is housed in a 14-pin SOIC package and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent SPST channels for signal routing
- Supports low-voltage single-supply operation down to 2 V
- Provides low on-state resistance for minimal signal loss
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal path switching
- Instrumentation input selection
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure the component meets required environmental standards such as RoHS compliance before integration into final assemblies.
Selection Notes
Select this component when multiple independent signal paths require switching within a compact footprint. Consider the 10 Ohm on-resistance and 35 mA current limit to ensure compatibility with source impedance and load requirements.
Part Context
This part belongs to the TS12A series of CMOS analog switches. It shares functional similarities with other members like the TS12A4515, though channel count and pinout configurations differ. The DR suffix indicates a specific surface-mount packaging variant.
Replacement Considerations
The TS12A4515DRG4 is a documented alternative within the same product family, offering similar electrical characteristics but with a different channel configuration and package style.
