CY74FCT827T - 10-Bit Buffers/Drivers with 3-State Outputs

The \x92FCT827T devices are 10-bit bus drivers that provide high-performance bus-interface buffering for wide data/address paths or buses carrying parity. The 10-bit buffers have NANDed output enables for maximum control flexibility. The \x92FCT827T devices are designed for high-capacitance-load drive capability, while providing low-capacitance bus loading at both inputs and outputs. All outputs are designed for low-capacitance bus loading in the high-impedance state.

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