The SGM2258 is a high-performance, dual, single-pole/ double-throw (SPDT) CMOS analog switch designed for switching USB 1.1 signals. High bandwidth and low
on-resistance make this switch able to pass both USB low- and full-speed signal with minimum signal distortion.
The SGM2258 features guaranteed on-resistance matching (0.3Ω TYP) between switches and guaranteed on-resistance flatness over the signal range (2Ω TYP). This ensures excellent linearity and low distortion when switching signals.
The device is fabricated with sub-micron CMOS technology to achieve fast switching speeds and designed for break-before-make operation. The select input is TTL-level compatible.
