CY74FCT2541T  
SCCS041A - September 1994 - Revised June 2000  
8-Bit Buffer/Line Driver  
• Extended commercial temp. range of –40˚C to +85˚C  
• Three-state outputs  
Features  
Function and pinout compatible with FCT and F logic  
Functional Description  
FCT-C speed at 4.1 ns max.  
FCT-A speed at 4.8 ns max.  
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.

Matched rise and fall times  
• Fully compatible with TTL input and output logic levels  
The outputs are designed with a power-off disable feature to  
allow for live insertion of boards.
