Overview
The TS12A4514D is a single-channel SPST analog switch manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. 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 DC switch current of 20 mA. Key timing parameters include a maximum turn-on time of 75 ns and a maximum turn-off time of 45 ns. The component functions within a temperature range of -40°C to +85°C, with a maximum power dissipation of 471 mW and a maximum supply current of 200 nA.
Feature Summary
- Single-pole single-throw (SPST) configuration for signal routing
- Low on-state resistance for minimal signal loss
- CMOS technology enabling low power consumption
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal switching
- Programmable gain amplifier input selection
Procurement Notes
Verify the specific suffix 'D' indicates the SOIC-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the supplier provides valid traceability records for quality assurance purposes.
Selection Notes
Select this component for applications requiring low voltage operation and single-channel switching. Compare the 10 Ohm on-resistance against system requirements to ensure signal integrity. Verify that the 12 V maximum supply voltage aligns with the available power rails in the target circuit design.
Part Context
This part belongs to the TS12A4514 series of low-voltage analog switches. It serves as a fundamental building block for signal path management in portable and battery-powered electronics where power efficiency and small form factor are critical constraints.
Replacement Considerations
Consult the Texas Instruments cross-reference guide for verified pin-compatible alternatives. Ensure any substitute maintains the same SOIC-8 footprint and electrical characteristics.
