PI5C6800

PI5C6800 10-Bit Bus Switch with Precharged Outputs Features Near-Zero propagation delay 5Ω switch connection between two ports Ultra-low quiescent power (0.2µA typ.) Ideally suited for notebook applications A port is hot swapable Packaging (Pb-free & Green available): – 24-pin 150-mil wide QSOP (Q) – 24-pin 173-mil wide TSSOP (L) Description Pericom’s Semiconductor’s PI5C6800 is a 10-bit bus switch with low On-State resistance. The bus switch creates no additional propagation delay. The switch is turned on by a single enable (ON) input. When ON is LOW, the switch is on and port A is connnected to port B. When ON is HIGH, the switch between port A and port B is open and the B port is precharged to BIASV through the equivalent of a 10-kΩ resistor.
