The 8282 and 8283 are 8-bit bipolar latches
with
3-state output buffers. They can be used
to
Implement latches, buffers
or
multiplexers. The 8283 inverts the input data at
its
outputs while the 8282 does not. Thus, all
of
the principal perlph
eral and input/output functions
of
a microcomputer system can
be
implemented
with
these devices.
