SGM2258 - Low-Power Full-Speed USB(12Mbps) Switch

General Description

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.

Key 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. SGM2258 is available in Green TQFN-2.1×1.6-10L package. It operates over an ambient temperature range of -40℃ to +.
