What are the key features of TS5A3159DCKTE4?
- Ultra-low 1.1 ohm on-resistance minimizes signal loss in analog switching paths
- Wide supply range of 1.65 V to 5.5 V enables use in 1.8 V, 3.3 V, and 5 V systems without separate level translation
- Compact SC-70 6-pin package with 63 dB off-state isolation ideal for space-constrained portable audio and data routing designs
What is TS5A3159DCKTE4 used for?
The TS5A3159DCKTE4 is well suited for portable consumer electronics and IoT devices that require low-loss analog signal routing between sensors, codecs, or communication buses at supply voltages from 1.65 V to 5.5 V. Its single-channel SPDT architecture simplifies multiplexing two signal sources to one output in battery-powered applications. High off-state isolation of 63 dB also makes it attractive for RF and audio switching stages where signal crosstalk must be minimized.

Frequently Asked Questions
What on-resistance and supply voltage range does the TS5A3159DCKTE4 offer for analog signal routing?
The TS5A3159DCKTE4 features a typical on-resistance of 1.1 ohm and operates from a 1.65 V to 5.5 V supply. This low on-resistance preserves signal integrity in audio and sensor paths, while the wide voltage range allows direct use in modern 1.8 V and 3.3 V microcontroller systems.
How does the 63 dB off-state isolation of the TS5A3159DCKTE4 benefit audio switching designs?
With 63 dB off-state isolation, the TS5A3159DCKTE4 suppresses signal feedthrough to levels below audible noise floors in most portable audio applications. This makes it suitable for headphone jack switching and codec input selection where crosstalk below -60 dB is required without external shielding components.
Is the SC-70 6-pin package of the TS5A3159DCKTE4 suitable for compact wearable PCB layouts?
Yes, the SC-70 6-pin package occupies roughly 2 mm x 2 mm of board space, making the TS5A3159DCKTE4 one of the smallest SPDT analog switches available for 1-channel switching at up to 5.5 V. Its small footprint is well matched to wearable devices and compact IoT modules requiring signal selection in under 4 mm² of PCB area.
