Functional Description
The ACT16240 contains sixteen inverting buffers with 3-
STATE standard outputs. The device is nibble (4 bits) con-
trolled with each nibble functioning identically, but indepen-
dently of the other. The control pins may be shorted
together to obtain full 16-bit operation. The 3-STATE out-
puts are controlled by an Output Enable (OE
each nibble. When OE

impedance mode, but this does not interfere with entering
new data into the inputs.
