Product Overview
TS5A3157 is a Texas Instruments single-pole double-throw analog switch for Signal_Chain routing. The switch connects COM to NO when the IN control input is high and connects COM to NC when IN is low. Recommended operating limits are 1.65 V to 5.5 V for V+, 0 V to V+ for switch I/O, and 0 V to 5.5 V for the control input.
The device is specified for -40°C to 85°C operation and has package options including DBV SOT-23-6 at 2.9mm x 2.8mm, DCK SC70-6 at 2mm x 1.5mm, and YZP DSBGA-6 at 1.75mm x 1.25mm. ON-state resistance varies with supply voltage, from 5.5 ohm typical at 4.5 V to 140 ohm typical at 1.65 V under the stated current conditions.
Dynamic and signal parameters include 6 ns typical turn-on time, 3.5 ns typical turn-off time, 2 ns typical break-before-make time, 300 MHz frequency response, -60 dB crosstalk, -57 dB feedthrough attenuation, 1 pC to 7 pC charge injection, and 0.01% total harmonic distortion under the listed test conditions.
