description/ordering informationThis octal buffer and line driver is designed specifically for low-voltage (3.3-V) VCC operation, but with the
capability to provide a TTL interface to a 5-V system environment.
The SN74LVT244B is 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.
ORDERING INFORMATION Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are
available at www.ti.com/sc/package.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
