ANALOGUE SW, SPDT, -40 TO 85DEG C; No. of Channels: 2Channels; Analogue Switch Type: SPDT; On State Resistance Max: 1.5ohm; Supply Voltage Range: 1.65V to 4.3V; Analogue Switch Case: UQFN; Available until stocks are exhausted
The FSA2258 is a high-performance, dual, Single Pole Double Throw (SPDT) analog switch that features low RON of 0.8Ω (typical) at 3.0V VCC. The FSA2258 operates over a wide VCC range of 1.65V to 4.3V and is designed for break-before-make operation. The select input is TTL-level compatible. The FSA2258 features very low quiescent current even when the control voltage is lower than the VCC supply. This feature suits mobile handset applications by allowing direct interface with baseband processor general-purpose I/Os with minimal battery consumption.
