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.
