description
The ’LVT16240 devices are 16-bit buffers and line drivers designed specifically for low-voltage (3.3-V) VCC
operation, but with the capability to provide a TTL interface to a 5-V system environment.
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 VCC 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 VCC through a pullup resistor;
the minimum value of the resistor is determined by the current-sinking capability of the driver.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

3.3-V ABT 16-BIT BUFFERS/DRIVERS
WITH 3-STATE OUTPUTS
SCBS717 – APRIL 2000
description (continued)
These devices are fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff 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.
The SN54LVT16240 is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74LVT16240 is characterized for operation from –40°C to 85°C.

† 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.
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
2. This current flows only when the output is in the high state and VO > VCC.
3. The package thermal impedance is calculated in accordance with JESD 51.
