ProductDescription

PericomSemiconductor’sPI3Cseriesoflogiccircuitsareproduced

using the Company’s advanced submicron CMOS technology,

achieving industry leading performance.

The PI3C6800 is a 10-bit bus switch with low on-state resistance.

Thebusswitchcreatesnoadditionalpropagationdelay.Tominimize

live-insertion noise, the device also precharges the B port to a user-

selectable bias voltage (BIASV).

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-kΩresistor.
