Functional DescriptionThese 16-bit buffers/line drivers are designed for usein
memory driver, clockdriver, orother bus interface applications,
where high-speed and low power are required. With
flow-through pinout and small shrink packaging board layout simplified. The three-state controls are designedto allow
4-bit, 8-bit or combined 16-bit operation.
This device is fully specified for partial-power-down
applications usingIoff. TheIoff circuitry disables the outputs,
preventing damaging current backflow 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 resistorsin the outputs. This reduces the
needfor external terminating resistors and providesfor mini-
mal undershoot and reduced ground bounce. The
CY74FCT162244T is ideal for driving transmission lines.
The CY74FCT162H244Tisa 24-mAbalanced output partthat
has “bus hold”on the data inputs. The device retains thein-
put’s last state whenever the input goesto high impedance.
This eliminates the needfor pull-up/down resistors and pre-
vents floating inputs.
