Product Overview
TS5A3159 is a Texas Instruments Signal_Chain device described as a 1-ohm SPDT analog switch. Its single-pole double-throw configuration routes a common analog node between normally open and normally closed switch paths, with switch input/output voltage specified from 0 V to V+ and control input voltage from 0 V to 5.5 V.
The device operates from a 1.65-5.5 V supply over -40 to 85 °C. At V+ = 4.5 V and TA = 25°C, ON-state resistance is 0.75 ohm typical and 1.1 ohm maximum, with 0.1 ohm typical resistance matching. Dynamic parameters include 20 ns typical turn-on time, 15 ns typical turn-off time, and break-before-make timing of 1 ns minimum, 12 ns typical, and 14.5 ns maximum.
Package options are SOT-23 (6) at 2.90 mm x 1.60 mm and SC70 (6) at 2.00 mm x 1.25 mm. Signal-chain use cases are supported by 100 MHz bandwidth, -65 dB OFF isolation, -65 dB crosstalk, 0.01% THD, and ratings for ±200 mA ON-state switch current.
