−3d B bandwidth: >720MHz
controllers with limited USB I/Os. The wide bandwidth
Low power consumption (1µA max)
(>720MHz) of this switch allows signals to pass with min-
Control input: LVTTL compatible imum edge and phase distortion. Superior channel-to-
Bi-directional operation channel crosstalk results in minimal interference. It is compatible with the high-speed USB 2.0 standard.
