CY54/74FCT540T  
CY54/74FCT541T  
8-Bit Buffers/Line Drivers  
Features  
Functional Description  
• Function, pinout and drive compatible with FCT and  
The FCT540T inverting buffer/line driver and the FCT541T  
non-inverting buffer/line driver are designed to be employed  
as memory address drivers, clock drivers, and bus-oriented  
transmitters/receivers. The devices provide speed and drive  
capabilities equivalent to their fastest bipolar logic  
counterparts while reducing power dissipation. The input and  
output voltage levels allow direct interface with TTL, NMOS,  
and CMOS devices without external components.  
F logic  
• FCT-C speed at 4.1 ns max. (Com’l)  
FCT-A speed at 4.8 ns max. (Com’l)  
• Reduced V  
(typically = 3.3V) versions of equivalent  
OH  
FCT functions  
• Edge-rate control circuitry for significantly improved  
noise characteristics  
• Power-off disable feature  
• ESD > 2000V  
The outputs are designed with a power-off disable feature to  
allow for live insertion of boards.  
• Matched rise and fall times  
• Fully compatible with TTL input and output logic levels  
• Sink current  
Source current  
64 mA (Com’l), 48 mA (Mil)  
32 mA (Com’l), 12 mA (Mil)  
• Extended commercial range of −40°C to +85°C

Notes:  
1. H = HIGH Voltage Level  
L = LOW Voltage Level  
X = Don’t Care  
Z = High Impedance  
2. Unless otherwise noted, these limits are over the operating free-air temperature range.  
3. Unused inputs must always be connected to an appropriate logic voltage level, preferably either VCC or ground.  
4. TA is the “instant on” case temperature.  
5. Typical values are at VCC=5.0V, TA=+25°C ambient.  
6. This parameter is guaranteed but not tested.  
7. Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample  
and hold techniques are preferable in order to minimize internal chip heating and more accurately reflect operational values. Otherwise prolonged shorting of  
a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parametric tests. In any sequence of parametric  
tests, IOS tests should be performed last.
