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
