Functional Description
The LVT16240 and LVTH16240 contain sixteen inverting buffers with 3-STATE standard outputs. The device is nibble
(4-bits) controlled with each nibble functioning identically, but independent of the other. The control pins may be shorted
together to obtain full 16-bit operation. The 3-STATE outputs are controlled by an Output Enable (OE
