description  
The ’LVTH162240devices are 16-bit buffers/drivers designed specifically for low-voltage (3.3-V) V operation  
CC  
and to improve both the performance and density of 3-state memory address drivers, clock drivers, and  
bus-oriented receivers and transmitters. They have the capability to provide a TTL interface to a 5-V system  
environment.  
These devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer and provide inverting  
outputs and symmetrical active-low output-enable (OE) inputs.  
The outputs, which are designed to source or sink up to 12 mA, include equivalent 22-series resistors to  
reduce overshoot and undershoot.
