74CBTLVD3245

8-bit level-shifting bus switch with output enable

The 74CBTLVD3245 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 I_OFF. The I_OFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
