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-
