These octal buffers/drivers are designed specifically for low-voltage (3.3-V) VCC operation with the capability to provide a TTL interface to a 5-V system environment.
These devices are organized as two 4-bit line drivers with separate output-enable () inputs. When is low, the device passes data from the A inputs to the Y outputs. When is high, the outputs are in the high-impedance state.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74LVTZ244 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
