LAST VALUE LATCH  
20 ACTIVE BUS TERMINATORS  
(BUS HOLD)  
FEATURES:  
DESCRIPTION:  
• Active termination pulls bus pins to rails  
• Holds last value of input signal  
• Ideal replacement for resistive termination  
• Ultra low 3µA DC quiescent current  
• Bus-hold eliminates floating bus lines and reduces static  
power consumption  
TheQS3389providesasetof20activeterminationcircuitswhichpulldata  
bussignalstothevoltagerails.Thisfeaturepreventsbussignalsfromfloating  
in the threshold region of standard TTL I/O devices. The QS3389 can  
replaceresistorterminationsolutionswhichaddDCpowerdissipationand  
increase component count. Input clamp diodes help to reduce reflections  
andundershootintransmissionlineenvironments. Importantly, thetermi-  
natorcircuitspullsignalstowhicheverlogicstatethesignalpreviouslyheld  
(high or low). For this reason, this device is also referred to as a last value  
latch.Thisdeviceisappropriatefordatabusapplicationswhereinterfacing  
devices have CMOS inputs with low input currents. These terminators  
provide sufficient drive to overcome leakage currents and drive corre-  
sponding signals away from the TTL threshold region.  
• Low power QCMOS technology  
• Operates over 2.7V to 5.5V Vcc range  
• TTL-compatible input and output levels  
• No added noise or ground bounce  
• 20 independent terminator circuits  
• Available in QSOP package  
The QS3389 is characterized for operation at 0°C to +70°C.  
APPLICATIONS:  
• Bus termination  
• Extend data hold time
