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.
This device is fully specified for partial-power-down
applications using I
preventing damaging current backflow through the device
when it is powered down.
The
CY74FCT16823T
high-capacitance loads and low-impedance backplanes.
= 5V,
The CY74FCT162823T has 24-mA balanced output drivers
CC
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.
