description  
The SN54LVTH16244A and SN74LVTH16244B devices are 16-bit buffers and line drivers designed for  
low-voltage (3.3-V) V operation, but with the capability to provide a TTL interface to a 5-V system  
CC  
environment. These devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. These  
devices provide true outputs and symmetrical active-low output-enable (OE) inputs.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.  
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.  
These devices are fully specified for hot-insertion applications using I and power-up 3-state. The I circuitry  
off  
off  
disables the outputs, preventing damaging current backflow through the devices when they are powered down.  
The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,  
which prevents driver conflict.
