description
These octal buffers/drivers are designed
specifically for low-voltage (3.3-V) V
CC
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 (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.
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.
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 85
