Description
Pericom鈥檚 Semiconductor鈥檚 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-k鈩?resistor.
