16-Bit Buffers/Line Drivers
Functional Description
These 16-bit buffers/line drivers are designed for use in
memory driver,clockdriver,or otherbusinterfaceapplications,
where high-speed and low power are required. With
flow-through pinout and small shrink packaging board layout
is simplified. The three-state controls are designed to allow
4-bit, 8-bit or combined 16-bit operation.
This device is fully specified for partial-power-down
applications using I
preventing damaging current backflow through the device
when it is powered down.
TheCY74FCT16244Tisideallysuitedfordriving
high-capacitance loads and low-impedance backplanes.
The CY74FCT162244T has 24-mA balanced output drivers
with current limiting resistors in the outputs. This reduces the
need for external terminating resistors and provides for minimalundershoot andreduced groundbounce. The
CY74FCT162244T is ideal for driving transmission lines.
TheCY74FCT162H244T isa 24-mAbalanced output part that
has “bus hold” on the data inputs. The device retains the input’s last state whenever the input goes to high impedance.
This eliminates the need for pull-up/down resistors and prevents floating inputs.
2. H = HIGH Voltage Level. L = LOW Voltage Level. X = Don’t Care. Z = High Importance.
3. Operationbeyondthe limitssetforthmay impairtheuseful life ofthedevice. Unlessotherwise noted, these limits areover the operatingfree-air temperature range.
4. Unused inputs must always be connected to an appropriate logic voltage level, preferably either V
(Above which the useful life may be impaired. For user
guidelines, not tested.)

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check 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 compatible) as defined above.
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)
