Functional Description
The FCT841T bus interface latch is designed to eliminate the
extra packages required to buffer existing latches and provide
extra data width for wider address/data paths or buses
carrying parity. The FCT841T is a buffered 10-bit wide version
of the FCT373 function.
The FCT841T high-performance interface is designed for
high-capacitance
load
drive
low-capacitance bus loading at both inputs and outputs.
Outputs are designed for low-capacitance bus loading in the
high impedance state and are designed with a power-off
disable feature to allow for live insertion of boards.
