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. 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 SN54HC259 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74HC259 is
characterized for operation from -40°C to 85°C.
