Description

General part information

74FCT825 Series

This bus-interface register is 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 CY74FCT825T is an 8-bit buffered register with all the CY74FCT823T controls, plus multiple enables (OE\1, OE\2, OE\3) to allow multiuser control of the interface, e.g., CS\, DMA, and RD/WR\. This device is ideal for use as an output port requiring high IOL/IOH.

This device is designed for high-capacitance load drive capability, while providing low-capacitance bus loading at both inputs and outputs. Outputs are designed for low-capacitance bus loading in the high-impedance state.

This device is fully specified for partial-power-down applications using Ioff. The Ioffcircuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
