Drive Features for LVCH16260A:  
All pins of the 12-bit Bus Exchanger can be driven from either 3.3V or  
5V devices. This feature allows the use of the device as a translator in a  
mixed3.3V/5Vsupplysystem.

High Output Drivers: ±24mA  
Reduced system switching noise  
APPLICATIONS:  
• 5V and 3.3V mixed voltage systems  
• Data communication and telecommunication systems  
The LVCH16260Ahas beendesignedwitha ±24mAoutputdriver.The  
driver is capable of driving a moderate to heavy load while maintaining  
speedperformance.  
DESCRIPTION:  
The LVCH16260A tri-port bus exchanger is built using advanced dual  
metal CMOS technology. The LVCH16260A is a high-speed 12-bit latched  
The LVCH16260A has “bus-hold” which retains the inputs’ last state
