Functional Description
The FCT2541T is an octal buffer and line driver designed
to be employed as a memory address driver, clock driver,
and bus-oriented transmitter/receiver. On-chip termination resistors
have been added to the outputs to reduce system noise caused by
reflections. The FCT2541T can be used to replace the FCT541T to
reduce noise in an existing design. The speed of the FCT2541T is
comparable to bipolar logic counterparts while reducing power dis-
sipation. The input and output voltage levels allow direct interface
with TTL and CMOS devices without external components.
The outputs are designed with a power-off disable feature to
allow for live insertion of boards.
