description/ordering information
This octal buffer and line driver is designed specifically for low-voltage (3.3-V) V_CC 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.
