8-Bit Addressable Latches
General Description
These 8-bit addressable latches are designed for general
purpose storage applications in digital systems. Specific
uses include working registers, serial-holding registers,
and active-high decoders or demultiplexers. They are mul-
tifunctional devices capable of storing single-line data in
eight addressable latches, and being a 1-of-8 decoder or
demultiplexer with active-high outputs.
Four distinct modes of operation are selectable by control-
ling the clear and enable inputs as enumerated in the func-
tion table. In the addressable-latch mode, data at the data-
in terminal is written into the addressed latch. The
addressed latch will follow the data input with all unad-
dressed latches remaining in their previous states. In the
memory mode, all latches remain in their previous states
and are unaffected by the data or address inputs. To elimi-
nate the possibility of entering erroneous data in the
latches, the enable should be held HIGH (inactive) while
the address lines are changing. In the 1-of-8 decoding or
demultiplexing mode, the addressed output will follow the
level of the D input with all other outputs LOW. In the clear
mode, all outputs are LOW and unaffected by the address
and data inputs.
