Functional Description
The FCT827T 10-bit bus driver provides high-performance
bus interface buffering for wide data/address paths or buses
carrying parity. The 10-bit buffers have NAND-ed output
enables for maximum control flexibility. The FCT827T is
designedforhigh-capacitanceloaddrivecapability,whileproviding
low-capacitancebusloadingatbothinputsandoutputs.Alloutputs
are
designed
for
low-capacitance
high-impedance state and are designed with a power-off disable
feature to allow for live insertion of boards.
