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.
The FCT823T high-performance interface family can drive large capacitive
loads, while providing low-capacitance bus loading at both inputs and
outputs. All inputs have clamp diodes and all outputs are designed for lowcapacitance bus loading in high-impedance state.
