Product Description
Pericom Semiconductors PI3C series of logic circuits are produced
using the Companys advanced submicron CMOS technology,
achieving industry leading performance.
The PI3C6800 is a 10-bit bus switch with low on-state resistance.
The bus switch creates no additional propagation delay. To minimize
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-kΩ resistor.
