CY74FCT162827T
SCCS064B - August 1994 - Revised September 2001
20-Bit Buffers/Line Drivers
Functional Description
The CY74FCT16827T 20-bit buffer/line driver and the
CY74FCT162827T
20-bit
buffer/line
driver
provide
high-performance bus interface buffering for wide data/address
paths or buses carrying parity. These parts can be used as a single
20-bit buffer or two 10-bit buffers. Each 10-bit buffer has a pair of
NANDed OE for increased flexibility.
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 CY74FCT16827T is ideally suited for driving
high-capacitance loads and low-impedance backplanes.
The CY74FCT162827T has 24-mA balanced output drivers
with current-limiting resistors in the outputs. This reduces the
need for external terminating resistors and provides for
minimal undershoot and reduced ground bounce. The
CY74FCT162827T is ideal for driving transmission lines.
