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
multifunctional
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
controlling the clear (CLR) and enable (G) inputs
as
shown
in
the
function
table.
In
the
addressable-latch mode, data at the data-in
terminal is written into the addressed latch. The
addressed latch follows the data input with all unaddressed 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
eliminate the possibility of entering erroneous data in the latches, G should be held high (inactive) while the
address lines are changing. In the 1-of-8 decoding or demultiplexing mode, the addressed output follows 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.
The SN54ALS259 is characterized for operation over the full military temperature range of −55
°C to 125°C. The
SN74ALS259 is characterized for operation from 0
°C to 70°C.
