3.3-V ABT 16-BIT BUFFERS/DRIVERS
WITH 3-STATE OUTPUTS
SCBS142Q – MAY 1992 – REVISED OCTOBER 2005
DESCRIPTION/ORDERING INFORMATION
The 'LVTH16244A devices are 16-bit buffers and line drivers designed for low-voltage (3.3-V) V
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.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors
with the bus-hold circuitry is not recommended.
When V
However, to ensure the high-impedance state above 1.5 V, OE should be tied to V
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
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.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
(3) The current flows only when the output is in the high state and VO> VCC.
