Functional Description
The ACT18825 contains eighteen non-inverting buffers
with 3-STATE standard outputs. The device is byte con-
trolled with each byte functioning identically, but indepen-
dently of the other. The control pins may be shorted
together to obtain full 8-bit operation. The 3-STATE outputs
are controlled by an Output Enable (OE
n
) input for each
byte. When OE
n
is LOW, the outputs are in 2-state mode.
When OE
n
is HIGH, the outputs are in the high impedance
mode, but this does not interfere with entering new data
into the inputs.
