description  
The ’LVT16240 devices are 16-bit buffers and line drivers designed specifically for low-voltage (3.3-V) V  
operation, but with the capability to provide a TTL interface to a 5-V system environment.  
CC  
These devices are designed specifically to improve both the performance and density of 3-state memory  
address drivers, clock drivers, and bus-oriented receivers and transmitters.  
The devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. The devices provide  
inverting outputs and symmetrical active-low output-enable (OE) inputs.  
When V is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down.  
CC  
However, to ensure the high-impedance state above 1.5 V, OE should be tied to V  
through a pullup resistor;  
CC  
the minimum value of the resistor is determined by the current-sinking capability of the driver.
