Octal Transparent Latch, Three-State

Features  
Description  
• CD54/74FCT373, CD54/74FCT373AT - Non-Inverting  
The CD54/74FCT373, 373AT, and 533 octal transparent  
latches use a small-geometry BiCMOS technology. The output  
stage is a combination of bipolar and CMOS transistors that  
limits the output-HIGH level to two diode drops below VCC. This  
resultant lowering of output swing (0V to 3.7V) reduces power  
bus ringing (a source of EMI) and minimizes VCC bounce and  
ground bounce and their effects during simultaneous output  
switching. The output configuration also enhances switching  
speed and is capable of sinking 32mA to 48mA.  
• CD54/74FCT533 - Inverting  
• Buffered inputs  
• Typical Propagation Delay: 3.9ns at VCC = 5V,  
o
TA = +25 C, CL = 50pF (FCT373AT)  
• SCR-Latchup-Resistant BiCMOS Process and Circuit  
Design  
The CD54/74FCT373, 373AT, and 533 outputs are transpar-  
ent to the inputs when the Latch Enable (LE) is HIGH. When  
the Latch Enable (LE) goes LOW, the data is latched. The  
Output Enable (OE) controls the three-state outputs. When  
the Output Enable (OE) is HIGH, the outputs are in the high-  
impedance state. The latch operation is independent of the  
state of the Output Enable.  
• FCTXXX Types - Speed of Bipolar FAST®/AS/S;  
FCTXXXAT Types - 30% Faster than FAST/AS/S with  
Significantly Reduced Power Consumption  
• 48mA to 32mA Output Sink Current (Commercial/  
Extended Industrial)  
• Output Voltage Swing Limited to 3.7V at VCC = 5V  
• Controlled Output-Edge Rates
