TS5A3159ADCKRG4

Overview

The TS5A3159ADCKRG4 is a single-channel, 2:1 analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65V to 5.5V and features a maximum on-resistance of 900 milliohms. The device utilizes an SC-70-6 surface-mount package with dimensions of 2mm x 1.25mm x 0.9mm. Key electrical specifications include a turn-on time of 30ns, a turn-off time of 20ns, and a -3dB bandwidth of 100MHz. It supports bidirectional signal transmission from 0V to V+ with low charge injection of -20pC and off-state leakage current of 20nA. The component functions across a temperature range of -40°C to +85°C.

Feature Summary

• Provides powered-off protection to isolate signals when the supply voltage is zero.
• Features break-before-make switching action to prevent signal distortion during channel transitions.
• Offers high isolation performance in the off state with minimal leakage current.
• Supports 5.5V tolerant control inputs for compatibility with various logic levels.

Applications

• Portable audio equipment requiring low distortion signal routing
• Battery-powered consumer electronics with limited power budgets
• Automotive infotainment systems operating in harsh environments
• Industrial sensing instruments needing precise analog signal switching

Procurement Notes

Verify the G4 suffix indicates lead-free and RoHS compliance per Texas Instruments standards. Confirm the SC-70-6 package marking matches official datasheet diagrams. Ensure the ordering part number includes the 'R' suffix for tape-and-reel packaging if required for automated assembly processes. Cross-reference the manufacturer date code against current production status notices.

Selection Notes

Select this component when a single SPDT switch with sub-ohm on-resistance is required in a compact footprint. The 1.65V minimum supply voltage makes it suitable for modern low-voltage digital systems. Compare the 900 milliohm on-resistance against load requirements to ensure acceptable voltage drop. Consider the 100MHz bandwidth for high-frequency signal integrity needs in data acquisition paths.

Part Context

This part belongs to the TS5A3159A family of analog switches designed for portable applications. It shares functional similarities with the TS5A3159DCKR but differs in package type and specific electrical tolerances. The G4 suffix denotes environmental compliance modifications without altering the core circuit functionality. It serves as a direct replacement for older generations of single-pole double-throw switches in space-constrained designs.

Replacement Considerations

The TS5A3159ADCKTE4 is a verified equivalent part number offering identical electrical characteristics and pinout configuration. Both parts utilize the same SC-70-6 package and maintain compatibility with existing board layouts. Verify that the E4 variant meets the same lead-free and RoHS requirements as the G4 version before substitution.
