Functional Description
The LCX16240 contains sixteen inverting buffers with
3-STATE standard outputs. The device is nibble (4 bits)
controlled with each nibble functioning identically, but inde-
pendent of the other. The control pins may be shorted
together to obtain full 16-bit operation. The 3-STATE out-
Logic Diagram
puts 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.
