SN74LVTZ244
SN74LVTZ244 is 3.3-V ABT Octal Buffers/Drivers manufactured by Texas Instruments.
description
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 (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°C.
