description

These octal buffers and line drivers are 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.

9 10 11 12 13

The ’LVTT244 are organized as two 4-bit line

drivers with separate output-enable (OE) inputs.

When OE is low, the device passes data from the

A inputs to the Y outputs. When OE is high, the

outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN74LVTT244 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count

and functionality of standard small-outline packages in less than half the printed-circuit-board area.

The SN54LVTT244 is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74LVTT244 is characterized for operation from –40°C to 85°C.
