TS5A21366DCUR from Texas Instruments is a Integrated Circuit 5V, 1:1 (SPST), 2-channel, analog switch, 0.75Ω Ron, 1.8V compatible logic - Analog & precision switches & muxes. The TS5A21366 is a bidirectional, 2-channel, single-pole single-throw (SPST) analog switch that is designed to operate from 1.65-V to 5.5-V supply voltages. The device offers a low ON-state resistance and an excellent channel-to-channel ON-state resistance matching. The device has excellent total harmonic distortion (THD+N) performance and consumes very low power. The control pin can be connected to a low voltage GPIO allowing it to be controlled by 1.8-V signals. These features make this device ideal for portable audio applications. The TS5A21366 is available in a small, space-saving 8-pin DCU or RSE package, and is characterized for operation over the free-air temperature range of -40°C to 85°C.
The TS5A21366RSER from Texas Instruments is a 2-circuit SPST-NO switch Integrated Circuit with 1:1 switching and 1 Ω on-resistance, in an 8-UQFN (1.5x1.5) package.
