Overview
The TS12A4515D 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 with a maximum power dissipation of 471 mW. The device features a maximum on-state resistance of 10 Ohms and supports a DC switch current of 20 mA. Key timing specifications include a maximum turn-on time of 75 ns and a maximum turn-off time of 45 ns. It functions within a temperature range of -40°C to +85°C and draws a maximum supply current of 50 nA.
Feature Summary
- CMOS technology enables low power consumption and compatibility with standard logic levels.
- Low on-state resistance ensures minimal signal attenuation across the conduction path.
- Single-pole single-throw configuration provides simple signal routing control.
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal switching
- Battery-powered instrumentation
Procurement Notes
Verify the specific suffix 'D' confirms the SOIC-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to integration. Ensure the ordering quantity matches the reel packaging requirements specified by the supplier for this particular part number.
Selection Notes
Select this component for applications requiring low voltage operation and high isolation. Compare the 10 Ohm on-resistance against system loss budgets. Verify that the 12 V maximum supply voltage aligns with the available power rails. Consider the SOIC-8 footprint constraints during PCB layout planning.
Part Context
This part belongs to the TS12A4515 series of low-voltage analog switches. It shares electrical characteristics with the TS12A4515P but differs in package type, utilizing SOIC-8 instead of PDIP-8. The series is designed for portable and battery-operated equipment due to its low power profile.
Replacement Considerations
The TS12A4515P serves as a pin-compatible alternative if through-hole mounting is required. Other members of the TS12A451x family may offer different channel counts or configurations while maintaining similar electrical performance profiles.
