Overview
The TS5A23167DCURG4 is a dual single-pole single-throw (SPST) normally-closed analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.65V to 5.5V and features a typical on-resistance of 0.9Ω with a maximum of 1.1Ω. The device supports a -3dB bandwidth of 150MHz, with turn-on and turn-off delays of 7.5ns and 11ns respectively. It includes 5.5V tolerant control inputs and exhibits low charge injection of 6pC. Packaged in an 8-pin VSSOP, it functions within a temperature range of -40°C to +85°C.
Feature Summary
- Dual SPST configuration with normally-closed state for signal routing
- Low on-resistance of 0.9Ω typical value ensuring minimal signal loss
- High bandwidth of 150MHz suitable for video and audio applications
- 5.5V tolerant logic inputs allowing compatibility with various control voltages
Applications
- Portable audio equipment signal switching
- Audio and video signal routing systems
- Low-voltage data acquisition circuits
- Mobile phone peripheral management
Procurement Notes
Verify the G4 suffix indicates lead-free compliance and RoHS3 conformity as per Texas Instruments standards. Confirm the DCU package code matches the required 8-VSSOP footprint. Ensure the ordering part number aligns with the specific tape and reel quantity requirements for manufacturing integration.
Selection Notes
Select this component when a normally-closed dual SPST switch is required for low-voltage signal paths. Compare against the TS5A23166 series if a normally-open configuration is needed instead. Consider the 0.9Ω on-resistance and 150MHz bandwidth limits for high-frequency signal integrity requirements.
Part Context
This part belongs to the TS5A2316x family of dual SPST analog switches from Texas Instruments. It shares core electrical characteristics with the TS5A23167DCUR but includes the G4 suffix denoting environmental compliance. The family targets portable electronics requiring efficient signal path management under low power constraints.
Replacement Considerations
The TS5A23167DCUR is the primary equivalent without the environmental suffix. For normally-open variants, consider the TS5A23166 series. Verify pinout compatibility before substituting with other dual SPST devices from different manufacturers.
