Functional Description
The CY74FCT16841T and CY74FCT162841T are 20-bit
D-type latches designed for use in bus applications requiring
high speed and low power. These devices can be used as two
independent 10-bit latches, or as a single 10-bit latch, or as a
single 20-bit latch by connecting the Output Enable (OE) and
Latch (LE) inputs. Flow-through pinout and small shrink
packaging aid in simplifying board layout. The output buffers
are designed with a power-off disable feature to allow live
insertion of boards.
The
CY74FCT16841T
is
high-capacitance loads and low-impedance backplanes.
The CY74FCT162841T 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
CY74FCT162841T is ideal for driving transmission lines.
