DESCRIPTION:
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
FCT823 is a 9-bit wide buffered register with Clock Enable (EN) and Clear
(CLR) – ideal for parity bus interfacing in high-performance microprogram-
med systems.
capacitance 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.
