Functional Description
The CY74FCT16823T and the CY74FCT162823T 18-bit bus
interface registers are designed for use in high-speed,
low-power systems needing wide registers and parity. 18-bit
operation is achieved by connecting the control lines of the two
9-bit registers. Flow-through pinout and small shrink
packaging aids in simplifying board layout. The outputs are
designed with a power-off disable feature to allow live insertion
of boards.
The CY74FCT16823T is ideally suited for driving
high-capacitance loads and low-impedance backplanes.
The CY74FCT162823T 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
CY74FCT162823T is ideal for driving transmission lines.
