Overview
The TS5A21366DCURG4 is a dual single-pole single-throw (SPST) analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.65 V to 5.5 V and features an on-resistance of 0.75 Ω. The device supports 1.8 V compatible input logic, ensuring compatibility with low-voltage control systems. Key electrical parameters include a maximum switching time of 72 ns and a maximum off-time of 318 ns. It draws a maximum supply current of 9 µA and handles a DC switch current of 100 mA. The component is housed in an 8-pin VSSOP package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Low on-resistance for minimal signal attenuation
- Compatible with 1.8 V logic inputs
- Ultra-low power consumption
- High bandwidth performance
Applications
- Portable audio equipment signal routing
- Battery-powered measurement instruments
- Consumer electronics signal switching
Procurement Notes
Verify the G4 suffix indicates lead-free compliance and RoHS adherence according to Texas Instruments documentation. Confirm the specific VSSOP-8 package variant matches design requirements. Ensure the operating environment stays within the specified -40°C to +85°C range. Validate that the 1.65 V to 5.5 V supply range aligns with system power rails. Check datasheet revisions for any updates to electrical characteristics or pin configurations.
Selection Notes
Select this component when low on-resistance and high bandwidth are critical for signal integrity. The 1.8 V logic compatibility makes it suitable for modern low-voltage digital interfaces. Consider the 9 µA quiescent current for battery-operated applications requiring extended life. The dual SPST configuration allows independent control of two signal paths within a compact footprint.
Part Context
This part belongs to the TS5A21366 series of analog switches designed for space-constrained portable devices. The series emphasizes low power and fast switching speeds. The DCURG4 designation specifies the tape and reel packaging format and lead-free construction. It serves as a solution for signal multiplexing in mobile and handheld electronics.
Replacement Considerations
Check Texas Instruments documentation for direct replacements within the same family. Verify pinout compatibility before substituting with similar analog switches from other manufacturers. Ensure voltage ratings and on-resistance values meet or exceed original specifications.
