CY54/74FCT646T  
SCCS031 - July 1994 - Revised March 2000  
8-Bit Registered Transceiver  
Features  
Functional Description  
• Function, pinout, and drive compatible with FCT and  
F logic  
• FCT-C speed at 5.4 ns max. (Com’l)  
FCT-A speed at 6.3 ns max. (Com’l)  
• Reduced VOH (typically = 3.3V) versions of equivalent  
FCT functions  
• Edge-rate control circuitry for significantly improved  
noise characteristics  
• Power-off disable feature permits live insertion  
• Matched rise and fall times  
• Fully compatible with TTL input and output logic levels  
• ESD > 2000V  
The FCT646T consists of a bus transceiver circuit with  
three-state, D-type flip-flops, and control circuitry arranged for  
multiplexed transmission of data directly from the input bus or  
from the internal registers. Data on the A or B bus will be  
clocked into the registers as the appropriate clock pin goes to  
a HIGH logic level. Enable Control G and direction pins are  
provided to control the transceiver function. In the transceiver  
mode, data present at the high-impedance port may be stored  
in either the A or B register, or in both. The select controls can  
multiplex stored and real-time (transparent mode) data. The  
direction control determines which bus will receive data when  
the enable control G is Active LOW. In the isolation mode  
(enable Control G HIGH), A data may be stored in the B reg-  
ister and/or B data may be stored in the A register.  
• Sink current  
Source current  
64 mA (Com’l), 48 mA (Mil)  
32 mA (Com’l), 12 mA (Mil)  
The outputs of the FCT646T are designed with a power-off  
disable feature to allow for live insertion of boards.  
• Independent register for A and B buses  
• Extended commercial range of −40˚C to +85˚C
