Product Overview
The TS5A4595 is a Texas Instruments single-pole single-throw analog switch for Signal_Chain designs. Its function table defines a normally closed configuration, with IN=L turning the switch ON and IN=H turning it OFF. The device operates from a single 2 V to 5.5 V supply and passes analog signals from 0 to V+ through the NC and COM pins.
Electrical behavior is defined across both 5 V-class and 3 V-class supplies. At V+=4.5 V and TA=25°C, on-state resistance is 5 ohm typical and 8 ohm maximum, with 0.5 ohm typical flatness. At V+=3 V, on-state resistance is 9.5 ohm typical and 16 ohm maximum. Timing is in the nanosecond range, with 12 ns typical turn-on time at 4.5 V to 5.5 V and 20 ns typical at 2.7 V to 3.6 V.
The device is offered in 5-pin SOT-23 (DBV) or 5-pin SC-70 (DCK) packages for compact assemblies. Its 450 MHz bandwidth, low leakage ratings, charge injection specifications, capacitance values, and audio-band THD figures support analog signal routing, low-voltage signal switching, and source selection circuits.
