74CBTLV3245
8-bit bus switch with output enable
The 74CBTLV3245 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 when OE 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.
