SGM2258 Datasheet, PDF (1/11 Pages) SG Micro Corp – Full-Speed USB (12Mbps) Switch

SGM2258
4.5Ω, 300MHz, 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.
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.
SGM2258 is available in Green TQFN-2.1×1.6-10L
package. It operates over an ambient temperature range
of -40℃ to +85℃.
