DESCRIPTION/ORDERING INFORMATION (CONTINUED)
The 'LVT16244B devices are 16-bit buffers and line drivers designed for low-voltage (3.3-V) V
CC
operation, but
with 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. These devices provide true outputs and symmetrical
active-low output-enable (OE) inputs.

3.3-V ABT 16-BIT BUFFERS/DRIVERS
WITH 3-STATE OUTPUTS
SCBS716E–MARCH 2000–REVISED DECEMBER 2006
When V
is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 1.5 V, OE should be tied to V
CC
through a pullup resistor;
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
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.
