What is TS5A23157HRSER used for?
TS5A23157HRSER is designed for audio signal switching, USB 2.0 bus switching, and general-purpose analog multiplexing in smartphones, tablets, and portable media players requiring low on-resistance with minimal signal distortion. Its 1.65 V to 5.5 V supply range allows mixed-voltage system boards to switch signals between 1.8 V and 3.3 V domains without level shifting. Industrial test equipment and data acquisition front ends also use this switch to route analog inputs to multiple ADC channels while maintaining signal fidelity across the -40°C to 125°C temperature range.

Frequently Asked Questions
What on-resistance does TS5A23157HRSER provide and why does it matter for audio signal path designs?
TS5A23157HRSER achieves a typical on-resistance of 0.9 Ω, which contributes less than 0.1 dB of insertion loss when driving a 50 Ω or 600 Ω load in audio signal paths. This low resistance preserves audio signal integrity across the 20 Hz to 20 kHz bandwidth, making it suitable for headphone jack multiplexing and microphone routing in mobile devices.
Over what supply voltage range does TS5A23157HRSER operate and which logic families can directly drive its control inputs?
TS5A23157HRSER operates from 1.65 V to 5.5 V, accepting control signals from 1.8 V LDOs, 3.3 V LVCMOS logic, and 5 V TTL drivers without level-shifting circuits. This broad range makes it compatible with low-voltage application processors and microcontrollers used in portable consumer electronics and industrial embedded boards.
What continuous current per channel does TS5A23157HRSER support and how does this affect USB or power switching use cases?
Each channel of TS5A23157HRSER supports up to 2 A of continuous current, which is sufficient to carry USB 2.0 VBUS power lines rated at 500 mA to 900 mA with comfortable margin. Power switching for USB accessories, battery charger path selection, and load switching on 3.3 V rails are all within the device's 2 A rating at temperatures up to 85°C.
How does TS5A23157HRSER perform across industrial temperature extremes compared to commercial-grade analog switches?
TS5A23157HRSER is rated for operation from -40°C to 125°C, matching full industrial and automotive temperature requirements. Commercial-grade switches rated only to 85°C would exceed their thermal limits in engine compartment or outdoor enclosure environments, while TS5A23157HRSER maintains on-resistance below 2 Ω across the entire -40°C to 125°C range, ensuring consistent switching performance in harsh conditions.
