The FCT823T series is built using an advanced dual metal CMOS technology. The FCT823T series 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 FCT823T is a 9-bit wide buffered register with Clock Enable (EN) and Clear (CLR) ideal for parity bus interfacing in high-performance microprogrammed systems.
