This 16-bit buffer/driver is operational at 0.8-V to 2.7-V V_CC, but is designed specifically for 1.65-V to 1.95-V V_CC operation.

The SN74AUC16244 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 (OE) inputs.

To ensure the high-impedance state during power up or power down, OE should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

This device is fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
