TS5A23167DCUR

Overview

The TS5A23167DCUR is a dual single-pole single-throw (SPST) analog switch manufactured by Texas Instruments, housed in an 8-pin VSSOP package. It operates on a single supply voltage ranging from 1.65V to 5.5V and functions within a temperature range of -40°C to 85°C. The device features a typical on-state resistance of 0.9Ω with a maximum channel-to-channel matching of 40mΩ. Key electrical specifications include a -3dB bandwidth of 150MHz, charge injection of 6pC, and off-state leakage current of 20nA. Switching times are specified at 7.5ns for turn-on and 11ns for turn-off, ensuring efficient signal routing in low-voltage applications.

Feature Summary

• Features 5.5-V tolerant control inputs for flexible interfacing with various logic levels.
• Provides high isolation performance with -85 dB crosstalk at 1 MHz.
• Designed for low power consumption with minimal standby current draw.

Applications

• Portable audio equipment signal routing
• Audio and video signal switching systems
• Low-voltage data acquisition circuits

Procurement Notes

Verify the specific suffix DCUR corresponds to the Tape and Reel packaging configuration when sourcing components. Confirm that the order quantity aligns with standard reel sizes if bulk procurement is required. Ensure compatibility with surface mount assembly processes given the VSSOP form factor. Cross-reference manufacturer documentation for any recent product change notices affecting this part number.

Selection Notes

Select this component when a dual SPST configuration with normally closed contacts is required. Compare against the TS5A23166 if normally open functionality is preferred instead. Consider the 0.9Ω on-resistance for signal integrity requirements in sensitive analog paths. Evaluate the 1.65V minimum supply voltage against system power constraints.

Part Context

This part belongs to the TS5A2316x series of analog switches from Texas Instruments. It shares similar electrical characteristics with other members like the TS5A23166 but differs in contact state configuration. The series is designed for portable electronics requiring small footprints and low power operation.

Replacement Considerations

The TS5A23166DCUR serves as a functional substitute if normally open contacts are acceptable instead of normally closed. Verify pinout compatibility and electrical parameter overlaps before substitution.

FAQ

What is the default contact state of the TS5A23167DCUR?

The TS5A23167DCUR features normally closed (NC) contacts, meaning the signal path is connected when the control input is inactive.

Does the device support 5.5-V logic control signals?

Yes, the control inputs are rated for 5.5-V tolerance, allowing direct interface with 5-V logic systems even when operating at lower supply voltages.

What is the maximum operating temperature for this IC?

The device is rated for an ambient operating temperature range up to +85°C.
