Functional Description
The CY74FCT16827T 20-bit buffer/line driver and the
CY74FCT162827T
20-bit
high-performance bus interface buffering for wide data/address
pathsorbusescarryingparity.Thesepartscanbeusedasasingle
20-bit buffer or two 10-bit buffers. Each 10-bit buffer has a pair of
NANDedOEforincreasedflexibility.Theoutputsaredesignedwith
a power-off disable feature to allow for live insertion of boards.
The
CY74FCT16827T
is
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.
