Product Overview
The TS5A4597 is a Texas Instruments single-channel, single-pole single-throw analog switch in the Signal_Chain category. The switch path is NC to COM, with the logic table defining IN=L as ON and IN=H as OFF. It is intended for single-supply operation from 2 to 5.5 V, with analog signal handling from 0 to V+.
At 5 V and 25°C, the device has 8 ohm typical ON-state resistance, 1.5 ohm typical ON-resistance flatness, 17 ns typical turn-on time, and 14 ns typical turn-off time. Dynamic and signal-path parameters include 450 MHz typical bandwidth, -85 dB typical OFF isolation, 5 pC maximum charge injection, and 0.04% typical total harmonic distortion at 5 V.
The TS5A4597 is available as TS5A4597DBVR in 5-pin SOT-23 (DBV) tape and reel and TS5A4597DCKR in 5-pin SC-70 (DCK) tape and reel. Its operating temperature range is -40 to 85°C, with storage temperature from -65 to 150°C.
