Typical Applications
TS5A63157 is suitable for 6 applications: Battery-Powered Portable Devices, Hot-Swap and Hot-Plug Signal Switching, Audio Signal Routing, Test and Measurement Instrumentation, USB and Peripheral Port Multiplexing, Industrial Sensor Signal Selection.
Battery-Powered Portable Devices
In battery-powered portable products, the TS5A63157 routes audio, sensor, or charging signals while drawing minimal board space in a 6-pin SC-70 package. Its 1.65 V minimum supply supports single-cell Li-Ion and NiMH systems near end-of-discharge, and the powered-off isolation at V+ = 0 V prevents back-powering when the battery is removed while external lines remain connected, protecting downstream ICs.
Recommended
Hot-Swap and Hot-Plug Signal Switching
The TS5A63157's integrated overshoot/undershoot sensing actively prevents voltage differentials from developing at the I/Os, making it well-suited for hot-plug connectors where cables are mated while rails are absent. Isolation in powered-off mode (leakage at V+ = 0) ensures no sneak paths, and 5-V tolerant control inputs allow direct interfacing with logic rails independent of V+ level, simplifying sequencing design.
Recommended
Audio Signal Routing
With approximately 10 ohm on-resistance and low charge injection, the TS5A63157 switches audio signals between sources (e.g., headset versus speaker path) with minimal click-and-pop and insertion loss. Break-before-make switching guarantees the two source paths are never momentarily shorted, preventing audible glitches during source transitions in portable audio and headset-detection circuits.
Recommended
Test and Measurement Instrumentation
In bench and portable instruments, the TS5A63157 multiplexes test signals between measurement channels. Its 10-ohm RON and excellent RON flatness preserve signal amplitude accuracy, while low charge injection minimizes switching transients that could disturb sensitive analog front ends. The SC-70 footprint allows dense channel arrays directly at connector interfaces.
Recommended
USB and Peripheral Port Multiplexing
The TS5A63157 can switch USB data or accessory-detect lines between a host controller and an alternate peripheral. Powered-off protection ensures that a live cable attached to an unpowered device does not damage the switch or back-drive the bus, a common failure mode for unprotected switches. Overshoot/undershoot sensing adds robustness against ESD-adjacent events at the connector.
Recommended
Industrial Sensor Signal Selection
Industrial systems use the TS5A63157 to select between redundant or calibration signal sources. The wide 1.65 V to 5.5 V supply range fits both legacy 5 V and modern 3.3 V or 1.8 V PLC logic domains, and the device handles analog sensor levels as well as digital status lines. Its compact SC-70 package suits high-density terminal-side signal-conditioning boards.

Key Differentiators
- Powered-off isolation protects live signal lines (vs SN74LVC1G3157DBVR)
- Active overshoot/undershoot I/O sensing (vs TS5A3159QDBVRQ1)
- SC-70-6 footprint saves board area vs SOT-23-6 (vs TS5A3159QDBVRQ1)
Design Notes
Do not substitute an unprotected switch (e.g., SN74LVC1G3157 or Nexperia 74LVC1G3157) into designs where signal lines can be live while V+ is absent - the TS5A63157's powered-off isolation and overshoot/undershoot sensing are the primary reasons for selecting this part. Always confirm the exact DCK pin assignment from the TI datasheet package section before layout, since 6-pin SC-70 pin functions vary between TI switch families.
With 10 ohm typical RON, series signal attenuation is modest, but RON varies with signal amplitude and supply. At 1.8 V supplies, RON is higher than at 5 V; budget extra margin for level accuracy in precision analog paths. The low charge injection spec minimizes switching transients, but keep the COM node capacitance low to reduce glitch amplitude at the moment of switching.
Place a 100 nF ceramic decoupling capacitor within 2 mm of the V+ pin. Keep the COM trace short and guard adjacent high-dV/dt traces to prevent capacitive feedthrough into the analog path. For hot-swap applications, route NO/COM/NC away from power switching nodes, and add TVS/ESD protection (e.g., TPD4S012) on external connector-side nets.
