The 74FCT823A series is built using an advanced dual metal CMOS technology. The FCT823 bus interface registers are 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 74FCT823A is a 9-bit wide buffered register with Clock Enable (EN ) and Clear (CLR ) ideal for parity bus interfacing in high-performance microprogrammed systems.

The 74FCT823A high-performance interface family is designed for highcapacitance load drive capability, while providing low-capacitance bus loading at both inputs and outputs. All inputs have clamp diodes and all outputs are designed for low-capacitance bus loading in high-impedance
state.
