16-Bit Buffers/Line Drivers
Functional Description
These 16-bit buffer/line drivers are used in memory driver,
clock driver, or other bus interface applications, where high
speed and low power are required. With 鏗俹w-through pinout
and small shrink packaging, board layout is simpli鏗乪d. The
three-state controls are designed to allow 4-, 8-, or 16-bit
operation.
This device is fully speci鏗乪d for partial-power-down
applications using I
off
. The I
off
circuitry disables the outputs,
preventing damaging current back鏗俹w through the device
when it is powered down.
The CY74FCT16240T is ideally suited for driving
high-capacitance loads and low-impedance backplanes.
The CY74FCT162240T 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
CY74FCT162240T is ideal for driving transmission lines.
