Functional Description
The ACTQ18825 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 18-bit operation. The 3-STATE out-
puts are controlled by an Output Enable (OE
each byte. When OE
mode. When OE
impedance mode, but this does not interfere with entering
new data into the inputs.
