Description
The ’HC259 and ’HCT259 Addressable Latch features the
low-power consumption associated with CMOS circuitry and
has speeds comparable to low-power Schottky.
This latches three active modes and one reset mode. When
both the Latch Enable (
low (8-line Demultiplexer mode) the output of the addressed
latch follo ws the Data input and all other outputs are forced
low . When both
outputs are isolated from the Data input, i.e., all latches hold
the last data presented before the
high. A condition of
mode) allows the addressed latch’s output to follow the data
input; all other latches are unaffected. The Reset mode (all
outputs low) results when
LE) and Master Reset (MR) inputs are
MR and LE are high (Memory Mode), all
LE transition from low to
LE low and MR high (Addressable Latch
LE is high and MR is low.

http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS

Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
