Functional Description
The LCXH162244 contains sixteen non-inverting buffers
with 3-STATE standard outputs. The LCXH162244 data
inputs include active bushold circuitry eliminating the need
for pull-up resistors to hold unused or floating data inputs at
a valid logic level. The devise is also designed with 26
:
series resistors in the outputs. This design reduces line
noise in applications such as memory address drivers,
clock drivers and bus transceiver/transmitters. 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 (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.
