1. General description

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 currentsinking

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.
