Overview
The TS5A3167DCKRG4 is a single-channel, single-pole single-throw (SPST) normally-closed analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.65 V to 5.5 V and features a maximum on-resistance of 0.9 ohms. The device supports bidirectional signal transmission with low charge injection of 6 pC and an off-isolation of -85 dB at 1 MHz. It utilizes a 5-pin SC-70 package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Low on-resistance for minimal signal loss
- Bidirectional analog signal routing capability
- Low charge injection for high-fidelity switching
Applications
- Portable audio equipment
- Audio and video signal routing
- Low-voltage data acquisition systems
Procurement Notes
Verify the G4 suffix indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the SC-70-5 package type matches design constraints. Check datasheet for specific handling requirements regarding moisture sensitivity level and recommended soldering profiles during assembly.
Selection Notes
Select this component when a single SPST switch with low on-resistance is required in a compact footprint. Ensure the operating voltage stays within the 1.65 V to 5.5 V range. Consider the normally-closed configuration for default state requirements. Verify control input compatibility with system logic levels.
Part Context
This part belongs to the TS5A3167 family of low-power analog switches. It shares core specifications with variants like the TS5A3167DBVR but differs in packaging. The family is designed for portable applications requiring efficient power management and signal integrity in space-constrained environments.
Replacement Considerations
TS5A3167DCKR is a direct functional equivalent without the G4 suffix. Other family members include TS5A3167DCUR and TS5A3167DBVR, which offer different package options while maintaining identical electrical characteristics.
