10-bit bus switch with 5-bit output enables

The 74CBTLV3384 is a dual 5-pole, single-throw bus switch. The device features two output enable inputs (nOE) that each control five switch channels. The switches are disabled when the associated nOE input is HIGH. Schmitt-trigger action at control inputs makes the circuit tolerant of slower input rise and fall times. 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.
