Overview
The TS12A4515DRG4 is a low-voltage, low on-resistance single-pole single-throw (SPST) CMOS analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 12 V and features a maximum on-resistance of 10 Ohms. The device supports a DC switch current of 20 mA and draws a maximum supply current of 50 nA. Key timing specifications include a maximum turn-on time of 75 ns and a maximum turn-off time of 45 ns. It is housed in an SOIC-8 surface-mount package and functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Low on-resistance performance for minimal signal attenuation
- CMOS technology enabling ultra-low power consumption
- Single-channel SPST configuration for compact circuit integration
Applications
- Battery-powered portable instrumentation
- Signal routing in communication systems
- Data acquisition channels
Procurement Notes
Verify the component authenticity against the manufacturer's official datasheet specifications. Confirm that the SOIC-8 package dimensions and pinout align with the design requirements. Ensure the ordering suffix matches the requested reel or cut tape format. Check compliance documentation for RoHS status prior to final procurement decisions.
Selection Notes
Select this component when a single channel with low on-resistance is required for low-voltage applications. Consider the 2 V minimum supply voltage constraint during power budgeting. Evaluate the 10 Ohm on-resistance against signal integrity needs. Verify thermal dissipation capabilities within the specified temperature range for the target environment.
Part Context
This part belongs to the TS12A4515 series of analog switches. It shares the same functional architecture as variants like the TS12A4516D but differs in specific electrical characteristics or packaging options. The DRG4 suffix indicates the specific tape-and-reel packaging and lead-free composition defined by the manufacturer.
Replacement Considerations
Direct substitutes may include other Texas Instruments SPST switches with similar voltage ranges. Verify pin compatibility and on-resistance limits before swapping. Cross-reference datasheets for timing differences.
