FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The CBTLV3861 provides ten bits of high-speed bus switching with low
on-state resistance of the switch allowing connections to be made with
minimal propagation delay.
The device is organized as one 10-bit bus switch. When output enable
(OE) is low, the 10-bit bus switch is on and port A is connected to port B.
When OE is high, the switch is open and a high-impedance state exists
between the two ports.
To ensure the high-impedance state during power up or power down,
OE should be tied to VCC through a pullup resistor; the minimum value of
the resistor is determined by the current-sinking capability of the driver.
