description

The ’FCT827T 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

’FCT827T 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 Ioff. The Ioff circuitry disables the outputs,

preventing damaging current backflow through the device when it is powered down.
