The 74CBTLV3245-Q100 is an 8-pole, single-throw bus switch. The device features a single output enable input (OE) that controls eight switch channels. The switches are disabled whenOEis 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 IOFFcircuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
