Functional Description
The LCX32244 contains thirty-two 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 32-bit operation. The
3-STATE outputs are controlled by an Output Enable (OE
n
)
input for each nibble. When OE
n
is LOW, the outputs are in
2-state mode. When OE
n
is HIGH, the outputs are in the
high impedance mode, but this does not interfere with
entering new data into the inputs.
