2 / 7 page www.fairchildsemi.com 2 Functional Description The AC16244 and ACT16244 contain sixteen non-inverting buffers with 3-STATE standard outputs. The device is nib- ble (4 bits) controlled with each nibble functioning identi- cally, but independent of the other. The control pins can be shorted together to obtain full 16-bit operation. The 3-STATE outputs are controlled by an Output Enable (OEn) input for each nibble. When OEn is LOW, the outputs are in 2-state mode. When OEn is HIGH, the outputs are in the high impedance mode, but this does not interfere with entering new data into the inputs.
