74CBTLV3244BQ

8-bit bus switch with 4-bit output enables

The 74CBTLV3244 is a dual 4-pole, single-throw bus switch. The device features two output enable inputs (nOE) that each control four 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.
