description/ordering information

The SN74CBTLV3861 provides ten bits of

high-speed bus switching. The low on-state

resistance of the switch allows 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 the

high-impedance state exists between the two

ports.

This device is fully specified for partial-power-down applications using Ioff. The Ioff feature ensures that

damaging current will not backflow through the device when it is powered down. The device has isolation during

power off.

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.
