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 I_off. The I_off 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 V_CC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
