Functional Description
These 16-bit buffers/line drivers are designed for use in
memory driver, clock driver, or other bus interface applications,
where high-speed and low power are required. With
ow-through pinout and small shrink packaging board layout
is simplied. The three-state controls are designed to allow
4-bit, 8-bit or combined 16-bit operation.
This
device
is
fully
specied
for
partial-power-down
applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backow through the device
when it is powered down.
The
CY74FCT16244T
is
ideally
suited
for
driving
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 mini-
mal
undershoot
and
reduced
ground
bounce.
The
CY74FCT162244T is ideal for driving transmission lines.
The CY74FCT162H244T is a 24-mA balanced output part that
has “bus hold” on the data inputs. The device retains the in-
put’s last state whenever the input goes to high impedance.
This eliminates the need for pull-up/down resistors and pre-
vents oating inputs.
