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.

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