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
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
The SN54LVTZ244 is characterized for operation over the full
military temperature range of -55°C to 125°C. The
SN74LVTZ244 is characterized for operation from -40°C to
