10-bit bus switch with output enable

The 74CBTLV3861 is a 10-bit bus switch with one output enable (OE) input. When OE is LOW, the switch is closed and port A is connected to the B port. When OE is HIGH, the switch is disabled.

To ensure the high-impedance OFF-state during power-up or power-down, OE should be tied to the VCC through a pull-up resistor. The minimum value of the resistor is determined by the current-sinking capability of the driver.

Schmitt trigger action at control input makes the circuit tolerant to slower input rise and fall times across the entire VCC range from 2.3 V to 3.6 V.

This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
