The IDT octal buffer/line driver is built using an advanced dual metal
CMOS technology. The FCT2541T is similar in function to the FCT2244T,
except that the inputs and outputs are on opposite sides of the package. This
pinout arrangement makes these devices especially useful as output ports
for microprocessors and as backplane drivers, allowing ease of layout and
greater board density.
The FCT2541T has balanced output drive with current limiting resistors.
This offers low ground bounce, minimal undershoot, and controlled output
fall times, reducing the need for external series terminating resistors. The
FCT2541T is a plug-in replacement for the FCT541T.
