The low ON Resistance (R ON) of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. STMAV335 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. Moreover the device reduces the overall BOM costs by eliminating the need for more costly multi input-output controllers.
