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
