It is designed for very low cross-talk, low bit-to-bit skew, high channel-to-channel noise isolation and low I/O capacitance. The switch offers very little or practically no attenuation of the high speed signals at the outputs, thus preserving the signal integrity to pass stringent requirements. ■ Wide bandwidth minimizes www.DataSheet4U.com ■ Hot insertion capable ■ ■ Supports bi-directional operation -40°C to 85°C operating temperature range Applications ■ ■ Workstation PC and Notebook Table 1.
