74ALVC16244 74ALVCH16244 2.5 V / 3.3 V 16-bit buffer/line driver 3-state Rev. 6 22 July 2021 Product data sheet 1. General description The 74ALVC16244 74ALVCH16244 is a 16-bit buffer/line driver with 3-state outputs. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The device features four output enables (1OE, 2OE, 3OE and 4OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. This device is fully specified for partial power down applications using I . The I circuitry disables the output, preventing the OFF OFF potentially damaging backflow current through the device when it is powered down. The 74ALVCH16244 has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors. 2.
