description
These octal buffers and line drivers are designed
specifically for low-voltage (3.3-V) V
CC
operation,
but with the capability to provide a TTL interface to
a 5-V system environment.
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
CC
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.
