General Description
IDT5474FCT821B General Description
The FCT821 series is built using an advanced dual metal CMOS technology. The FCT821 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 74FCT821 is a buffered, 10-bit wide version of the popular FCT374 function.
The FCT821 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.
