Product data sheet
1. General description
The 74CBTLV3244 is a dual 4-pole, single-throw bus switch. The device Features two output enable inputs (n OE) that each control four switch channels. The switches are disabled when the associated n OE 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.
