The SN74ALVCH16244DGGR is a 16-bit Buffer/Driver with 3-state outputs and designed for 1.65 to 3.6V VCC operation. The SN74ALVCH16244 is designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers and bus-oriented receivers and transmitters. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. It provides true outputs and symmetrical active-low output-enable inputs. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver. Active bus-hold circuitry holds unused or un-driven inputs at a valid logic state. Use of pull-up or pull-down resistors with the bus-hold circuitry is not recommended.
Bus hold on data inputs eliminates the need for external pull-up/pull-down resistors
