Functional Description
The LCXZ162244 contains sixteen non-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 can be
shorted together to obtain full 16-bit operation. The
3-STATE outputs are controlled by an Output Enable (OE
input for each nibble. When OE
2-state mode. When OE
high impedance mode, but this does not interfere with
entering new data into the inputs.
