This bus-interface register is designed to eliminate the extra packages required to buffer existing registers and provide extra data width for wider address/data paths or buses carrying parity. The CY74FCT823T is a 9-bit-wide buffered register with clock-enable (EN\) and clear (CLR\) inputs that are ideal for parity bus interfacing in high-performance microprogrammed systems. It is ideal for use as an output port requiring high I_OL/I_OH.

This device is designed for high-capacitance load drive capability, while providing low-capacitance bus loading at both inputs and outputs. Outputs are designed for low-capacitance bus loading in the high-impedance state.

This device is fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
